8157

[DeanB]

I cannot find a manual or driver for an old HP8157A attenuator.  I figured out that the command ATT XX.X sets the attenuation, but I need to also set the wavelength.  WAV XXXX seemed logical, but doesn't work.  Anybody have a manual or driver for CVI?

Hi.

I found this with help from Google. I believe the 8156A and 8157A are similar devices, so hopefully the command syntax will be compatible.

Good luck.

The command set for 8157A is similar to 8158.

For example

query wavelength : wvl?
