For most mortal souls probing up to 12Ghz, Agilent’s integrated active probe system is called the the AutoProbe 1, which looks like this:
Regular full blown Windows-based Infiniium oscilloscopes takes any AutoProbe 1 probes (as long as the shape fits), but I noticed my DSO6104A (InfiniiVision 6000A series) do not take my 1152A (2.5Ghz) probes nor my fancy 1168A (10Ghz) and 1169A (12Ghz) probes.
Turns out the more compact, embedded (VxWorks) Agilent scopes that boots almost immediately. It’s called the InfiniiVision Series, which covers 1000 X-, 2000 X-, 3000A/T X-, 4000 X-, 6000 X-, 5000, 6000, and 7000 Series.
I’m not rich enough to get my hands on the X series, but I know from the architecture that 5000, 6000 and 7000 series are basically the same scope. 5000 and 6000 series looks almost identical while the 7000 series adds a giant screen and a slightly different keypad layout (the BNC ports do not align with the channel buttons and dials).
Turns out the datasheets shows two caveats:
- 100Mhz model uses different hardware. They don’t take Autoprobe interface as there’s absolutely no reason why you need an active probe to get 100Mhz single ended. Agilent skipped the hardware for it (thus the autoprobe pins) altogether although they kept the recessed space reserved for Autoprobe so they don’t have to mold a different front bezel just for the 100Mhz models.
- They basically take only Generation I AutoProbe I, namely the 1130 series
- Gen 0 (not an official name) AutoProbe 1 does not work: 1152A (2.5Ghz single ended) for 54845A. These differential probes: 1153A, 1154A, 1155A, 1159A are also considered too old. They were intended to work with old Infiniiums such as 54845A
- Gen 2 AutoProbe 1 (only 10Ghz 1168A/B and 12Ghz 1169A/B models) does not work. These embedded scopes usually max out at 1.5Ghz, with the exception that 6000X goes up to 6Ghz, which is still way below 10Ghz
- N2800 series are Autoprobe I, but it’s Gen III (has a bigger butt extending away from the AutoProbe I hole), so it doesn’t work
- The rest are Autoprobe II and III that’s beyond our mortal souls (and way out of the league of InfiniiVision scopes)
