The Bias current is very small and will show up as 0

Turning power ON

...

Make sure that the box to the right of the OFF/ON buttons are RED.

To turn on the low voltage power (DVDD, AVDD and V125) and the high voltage bias click the ON button next to the hybrid you want to power.

Note: there is often a very significant delay before the GUI updates after a change so be patient.

You should see currents on DVDD (~250mA) and AVDD(~350mA but sometimes ~500mA). The current on V125 will often be zero until the DAQ has configured the chips. The bias should ramp up and you should see it stopping at 180V.

One special feature is that the DVDD power is coupled between two hybrids (0&1,2&3, and so on). Thus you will see DVDD current of the other hybrid ON even though that hybrid is not "ON". This is expected and normal behavior.

Turning power OFF

...

Make sure that the box to the right of the OFF/ON buttons are GREEN.

To turn on the low voltage power (DVDD, AVDD and V125) and the high voltage bias click the OFF button next to the hybrid you want to power.

Note: there is often a very significant delay before the GUI updates after a change so be patient.

You should see all low voltage currents and high voltage bias ramping down.

One special feature is that the DVDD power is coupled between two hybrids (0&1,2&3, and so on). This means that powering down always results in powering down BOTH hybrids. This is expected and normal behavior.
