HP 16702A with 16701B expansion frame
« on: August 03, 2023, 09:25:35 pm »
Hi,

I have a HP 16702a and I extended it with a HP 16701B. Now I can use 10 cards in the logic analyzer.
The main system see the newly added frame, but didn't see the cards on the expansion frame. 'pv' said F to I is empty slots.
The card is working in the main frame. I need to change something on the main config? Or it is discover these cards automatically?

The catalog said that 16702A working with 16701B.

Anybody has same issue?

I think the cards should just show up in the expansion frame tab.

Are the fans on the 16701B running?

Any bent pins on the cable?

For a 16702B in combination with the16701B, the cards indeed just show up.

Perhaps a simple question, but do the cards you're trying in the 16701B work in your 16702A?

Hi MarkL

Of course I tested them with my 16702A. I tried different cards, but not helps...
The catalog said that 16701B works with 16702A.
See on the screen picture. Looks like that the system see the expansion frame, but not show the cards.
Stupid question, but no need to do a sw update, or install additional package for this? I checked the analyzer menu but I not found any useful for this. Maybe a voltage missing for the cards in expansion frame?

Hi aeg,

Yes the fans running well. The cable between the 2 unit is simple. or mixed the wires in the cable? I not found any info about this.
I will check the cable connections, but it's like an original and non possible to repair. No screws on the connector. Cable number is: 16701-61604

Hi MarkL and aeg,

Good news! Looks like working fine the extender. I cleaned the connectors with IPA and worked well. I surprised that only it's needed this. I thought any incompatible issue between the two unit.
