2.3 HV2916 ANALOG SWITCH EVALUATION BOARD SETUP PROCEDURE
To operate the HV2916 Analog Switch Evaluation Board, the following steps must be
completed:
1. Attach the HV2916 Analog Switch Evaluation Board to the HV MUX Controller
Board (ADM00825) with the J1 and J2 connectors.
2. Connect all the jumpers on J5, J6, J7 and J11 for the on-board R-C load.
3. Connect all the power supplies to the voltage supply input connectors J3 and J4,
as indicated in Table 2-1 , by observing the polarity.
4. Turn on the V
LL
first and then turn on the V

7. Connect a USB cable from the HV MUX Controller Board to the PC.
8. C12V/1A power to the HV MUX Controller Board and turn on OFF/ON
switch.
9. Run the HV MUX GUI software on the PC.
10. Click the
Initialize HV MUX Controller button in the GUI. This causes the status
window at the bottom of the screen to display an “Initialization Complete” message.
11. Clear the STBY check box and select the MODE check box. (Do not change
these states. Not used for the HV2916 Analog Switch Evaluation Board.)
12. Click the Set HV MUX button. All digital control signals are applied to the HV2916
device.
13. Set the number of pulses and T
OFF
time of the pulser.
14. Select CH1 or CH2 to set the Channel 1 pulser or the Channel 2 pulser,
respectively.
15. Click the Start button for the selected pulser to generate pulse bursts.
16. Click the Stop button for the selected pulser to stop generating pulse bursts.
