Agilent 54830 Infiniium Digital Oscilloscope Repair / Service / Upgrade 54830B, 54830D, 54831B, 54831M, 54831D, 54832B, 54832D

As time goes by, it seems like there’s quite a few small problems with the very well engineered 54830 series oscilloscope. These are all manageable (not core) problems and I believe I got the details down.

Models supported: 54830B, 54830D, 54831B, 54831M, 54831D, 54832B, 54832D
‘D’ means it’s a Mixed-Signal oscilloscope (comes with logic analyzer)
‘M’ is the military versions that’s exactly the same as ‘B’. The ‘M’ batch is for sure shipped with Windows 98.

I also support upgrading any Windows 98 based unit to Windows XP Pro.

I also have plenty of units and parts to get your problems fixed.

If it doesn’t power or boot, it might be a less severe problem than you think. Evaluation is always free. 

Trade in for a guaranteed unit

Serviced units (Motherboard corrected, replaced mechanical HDD to SSD, replaced CD-ROM with DVD writer, comes with LS-120 drive, Windows XP Pro installed, 2 years repair/exchange* warranty):

  • 54831M[$2999]: 600Mhz, 4GS/s
  • 54831M modded to 54832B [$3499]: 1GHz, 4GS/s.
  • 54832B [$3999]: 1GHz, 4GS/s
  • 54832D [$4499]: 1GHz, 4GS/s (Mixed Signal Oscilloscope with Logic Analyzer)

If your decaying unit is frustrating you, you can swap your it with the worry-free, fully serviced units by paying a $1500 difference to enjoy all the upgrade and peace of mind. 

* I’m likely to have a replacement unit for immediate exchange to get you up and running. In the unlikely event I run out of units, I’ll pay you $100/week delay if the repair takes more than 1 week, up to the full amount you’ve paid.

NOTE: This (swap) deal does not apply to units with a genuinely failed Acq board (like analog signal path/cal/trigger problems) or I confirmed that it has a failed power supply unit.

Parts cost (they are taken from fully working units, so there’s sacrifice):

  • Corrected VP22 motherboard [$699]
    [Subtract $200] if you trade in a defective VP22 (4 PCI slots).
    [Subtract $300] if you trade in a working M880 (3 PCI slots).
  • Old style interface card [$699]:
    [Subtract $200] if you trade in your working GPIB combo card.
    Old style interfaces works across the board. The combo only works on the latest acq boards.

Labor/Repair cost (all service guaranteed for 2 years). No cost if not successful:

  • Front-end problem (cannot calibrate) [$599 for first channel + $199/channel]. Parts included.
  • Cannot power up [$199]. Parts NOT included. Not charged if no actual repairs were made.
  • Boot problems [$199]. Waived if parts were bought to solve it.
  • Oscilloscope program hangs / BSOD [$199]. Waived if parts were bought to solve it.
  • Replace motherboard [$199]. Parts NOT included.

Upgrade / service cost

  • Upgrading from Windows 98 to Windows XP Pro [$499 for DIY, $699 for full service]: SSD included. This covers the self-calibration.

    If your unit comes with licenses, you will need to provide the license number (can easily do it yourself) to enable them. Can ask Keysight to look it up for you.

  • Modernize the unit [$299, $149 when combined with any repair/service/parts above]: migrate hard drive to SSD, replace CD-ROM with DVD drive, replace FDD with LS-120 drive (if applicable).

The prices are negotiable if more than one part/service is needed. 

Call me at 650-804-5024. I’m located in Irvine, CA. You’ll be responsible for all shipping costs for anything that’s not my fault.

Does the east coast have a ‘go fig’ culture?

Nearly a year ago I went for a company sponsored training at MIT and I toured around the Boston area. My first impression was that nobody in the east coast gives a damn about ‘ease of use’ issues (apparently it’s an artistic exaggeration, but you know what I mean). The signs were often wrong (contradictory), confusing or not at conspicuous places, ranging from traffic signs (lane markings are optional, plus there are plenty of last minute turns at acute angles) to the MIT summer program registration itself (intentionally not telling you where the classroom is located before you book the hotels, and there were no signs telling you how to get to the registration if you came from the back end of the building).

Here’s a funny example:

(In case if you didn’t notice, the buttons points down. Telling the people who uses it to ‘go straight to hell’, hehe.)

I understand the people in the east coast must be very smart given that they have to dance around the mess every day. For me, I’d rather focus my effort developing algorithms or solving engineering/business problems than sorting through the mess to get the basic information I need. 🙂

Tablet / Cell phone holder for Nissan Maxima 2001

While transferring to my new cell phone, I found a photo of my hack to create a 7″ tablet & 5.7″ cell phone holder for my Nissan Maxima 2001. It consisted of a tablet (or cell phone stand from eBay as pictured), two large binder clips and a pocket kleenex. Turns out you can use a packet of pocket Kleenex to extend the legs of the tablet/phone holder and have it snugly fit in the dummy space in the factory stereo bezel. The two binder clips was just to avoid the unit from sliding sideways. The trick is to use stick one hand of the binder clip to the gap at the sides of the front panel.

Test instrument repair services (Specific models only)

There are a few used test instrument models that I’m familiar with the common problems. I moved onto the higher end, big ticket items so I wouldn’t bother acquiring them anymore.

Nonetheless, it hurts to see a piece of good equipment going to landfill. I’d be happy to repair the following models at a moderate rate (materials included, no fix no pay) below if anybody is interested:

  • HP 6515A power supply: $400 for a problematic unit, $300 when you send in a good one for preventative recapping (the capacitors are from 1970s! They are dying.).
  • HP/Agilent 54600 series oscilloscope: display got squeezed ($200), unit losing memory/time ($200), blown input channels due to excessive voltage ($300 for 1 channel + $100 per extra channel), unstable/cannot trigger ($500).
  • HP/Agilent (Older, non-Megazoom) Infiniium series: replacing OS hard drive ($250), cannot calibrate certain channels ($400 for 1 channel + $100 per extra channel).
  • HP/Agilent Infinium 5483X and above: refer to 54830 series post.
  • TDS 500, 600, 700 series oscilloscope: SPC fail without other symptoms ($500), Acq/Attenuator fail ($600), Proc board fail ($400), Color screen bubbled ($500), Cal initialization failed ($300), upgrading all possible software options ($200, free with any other service).

Contact me at 650-804-5024. All units must be delivered to Irvine, CA for service (and shipped back/picked up) at requester’s cost.

Symantec Ghost in Windows hangs for mSATA to SATA adapter board Solution: Start Ghost with -NOTRIM

I was trying to image a mSATA SSD with Ghost in Windows (I’m using version Corporate Edition as I bought the Altiris license) and I ran into internal consistency error 8027 right at the very beginning of the copying process.

For some reason, it doesn’t happen if I boot to the DOS version (provided by Agilent) to do the cloning.

Luckily the status bar tells me what’s going on during the process. I notice it always hangs when ghost tells me that it’s TRIMming the SSD. I looked up the help file (ghost32.exe -help) and noticed that there’s a “-NOTRIM” option. Tried it and the clone completed successfully.

Turns out Symantec is aware of it. The title of the support article is called “Cloning Solid State Disk (SSD) drives fails when using the UEFI 12.0.0.x Ghost executables“.

The summary says it since older versions (11.5.1.x) does not have TRIM, this isn’t a problem, and

“Build (from GSS 3.0 early build) resolved the issue with the partition restore”

I’m not sure what it means. But the solution is the same as what I did: disable TRIM when copying SSD in Windows.

Create user account using email address (like your Microsoft account) in Windows 7/2008

If you live in a mixed environment of Windows 7 and 8/10 computers, you might want to set the usernames to be the same so you can share the files/printers without managing Homegroup.

Nonetheless, in Windows 7/2008, if you try to create a user account using the traditional tool (Local Users and Groups) in Computer Management, you are not allowed to use email address as user name because they banned the at-mark (@):

I searched the web for quite a while, came across stuff like UPN (User Principal Name) without luck (No active directory on Windows 7, nor I want to setup a domain controller in Windows 2008 for home network). Turns out the solution is dead simple: use the “User Account” from Control panel to create the user account. No questions asked!

Switch between 32-bit and 64-bit user written software like CVX

CVX is a very convenient convex optimization package that allows the user to specify the optimization objective and constraints directly instead of manually manipulating them (by various transformations) into forms that are accepted by commonly available software like quadprog().

What I want to show today is not CVX, but a technique to handle the many different versions of the same program targeted at each system architecture (32/64-bit, Windows/Mac/Linux). Here’s a snapshot of what’s available with cvx:

OS 32/64 mexext Download links
Linux 32-bit mexglx
64-bit mexa64
Mac 32-bit mexmaci
64-bit mexmaci64
Windows 32-bit mexw32
64-bit mexw64

You can download all packages for different architectures, but make a folder for each of them by their mexext() name. For example, 32-bit Windows’ implementation can go under /mexw32/cvx. Then you can programmatically initialize the right package for say, your startup.m file:

run( fullfile(yourLibrary, mexext(), 'cvx', 'cvx_startup.m') );

I intentionally put the /[mexext()] above /cvx, not the other way round because if you have many different software packages and want to include them in the path, you can do it in one shot without filtering for the platform names:

addpath( genpath( fullfile(yourLibrary, mexext()) ) );

You can consider using computer(‘arch’) in place of mexext(), but the names are different and you have to name your folders accordingly. For CVX, it happens to go by mexext(), so I naturally used mexext() instead.
