9. If there is no waveform, and the supply current drops to zero, check if Shutdown Indicator is lighting up, check
which limit is causing the shutdown through the Protection Panel, remove the alarm event, and click Shutdown
Reset.
10. To stop the output waveform, turn off/disable the SYNC clock from the external function generator.
Using the Arbitrary Waveform Generation Mode
The AWG mode is analogous to the operation of an arbitrary waveform generator. This mode is useful in generating
waveforms that cannot be achieved from 16 levels. This mode provides versatility of usage and active control of the
waveform. This mode is only available for the FMC connected board
mode of operation.
1. Implement these changes to the AD8460 evaluation board:
a. Use the SDP-H1 board with the FMC connector.
b. Set the SYNC frequency from an external function generator to 20 MHz.
c.

Note: The SYNC signal is also routed to the FPGA on the SDP-H1 board. The minimum frequency for
this FPGA operation is 19 MHz.
Supply +/− 25 V or more
a. Use the Input Mode Switch to select the AWG mode.
b. Wake the AD8460 HVDAC by unticking the HV DAC SLEEP box.
c. Click Apply Changes.
d. Click on Proceed to AWG TX o advance to the vector transmission tab.
e. Click on Vectors... to advance to the Vector Generator tab.
f. A default single tone vector window pops up, as shown in
Figure 24. Default Single Tone Vector Setup
(Table 1). The following are the steps to use this
