Functional Check
Perform the following procedure to determine if the module is operating
correctly. For this procedure, you will need a television monitor to view the
generator signals.
1. If the module is not installed in the TG 2000 mainframe, use the installation
procedures in
Appendix D: Hardware Installation .
2. Cycle instrument power. The mainframe runs a self test on all modules.
To determine if the self test was successful, push the Module button and see
if the AWVG1 module icon appears. If you have more than one AWVG1
Generator module installed, check the slot number on the display to be sure
the module you are checking appears.
3. If necessary, install signal sets into the module using the procedure on
page D--6. Be sure that you have the Bullseye signal installed.
4. Connect your monitor to the Output 1 BNC connector on the AWVG1
Generator module rear panel, and terminate the monitor’s loop-through
connector in 75
Ω
.
5. Terminate the AWVG1 Generator module outputs 2 and 3 in 75
Ω
. (This is
necessary for the module self cal.)
6.
Wait 20 minutes for the instrument to warm up.
7. Push the Utilities button, and then do the following:
a. Touch Module Self Cal on the display.
b. Touch the self-cal icon for the module you are testing.
c. Touch Start Cal on the display.
The Self Cal takes 2 to 5 minutes, depending on the module. An error
message indicates a failed calibration. If the Self Cal fails, contact your
Tektronix representative for assistance.
8.
Push the
Modules
front-panel button and touch
AWVG1
on the display.
9. Select a signal set that is compatible with your monitor, and then touch the
Zoneplate icon to select the Bullseye signal as the output signal. Selecting
the signal automatically ensures that the module output is enabled.
10. Adjust your monitor to view the signal. Check that a circle signal appears,
similar to the signal shown in Figure 1--2.
