34925A MUX bank switching avoidance during 60 channel scan

Hi,

 

I am using the Agilent 34925A MUX module within the 34980A mainframe to scan for DC Voltages.  I want to scan 60 channel at the same time. When i do it, It produces a relay switching, which is due to (i think) switching in 34925A from bank 1 to bank 2.

 

 

I want to avoid that relay switching for two reseasons, first, it is very annoying and other is, it will degrade relay and consiquently module earlier.

 

My question is, Is there any way to scan 60 channels by using 34925A without relay switching?

 

 

Any help will be appreciated!

Without relay switching how are you envisioning that you can scan 60 channels?

thanks nyc for your indirect answer (NO)

 

actually, it is bit strange that a single electronics unit do a lot of mechanical switching during its normal operation. therefore, i was thinking that, there might be some solution in form of updated software or some other 34925A equivalent hardware or any other module factory suggestion, any thing. there should be some solution

 

dear just tell me one thing, what will be your feeling when you will be using 1000$ module with the continous fear of early degradation?   

 

In my view, this module is ment for single wire 80 channels, so i have right to operate this module with peace of mind. do't you think

I have no idea what you are saying.

 

To be able to measure 60 different channels with one DMM, relays are needed.

If you don't like Agilent's implementation, you are certainly welcome to design and build your own.

Software can't make up for that major hardware architecture fiasco.  Want to read from 60 channels?  Sounds like a good job for a 6225.

You need to complain to Keysight about their architecture. It does seem strange that a board with solid state relays would use mechanical relays for bank switching so ask them. The manual should help as well and also provide a typical lifetime of any mechanical relays. This question has nothing to do with any NI product.
