Using Time Domain Mode
Time Domain mode is an option available for the BDS receiver. The Time Domain mode allows unprecedented
visibility into the shape of pulsed RF waveforms in the non 50-Ohm environment. Very similar to an oscilloscope, the
BDS will display a one-shot, triggered view of the pulse envelope. Very different from an oscilloscope, the BDS will
display the waveform in voltage, current, phase, power, or impedance to the fully-specified accuracy of the system.
Selecting the Time Domain FPGA Image
Note:
A Time Domain option license must have been installed to allow selection of the Time Domain
FPGA. See
"Installing a BDS Receiver Option License" on page 15
.
The BDS Receiver will not allow selection of the Time Domain Mode until the Time Domain FPGA Image is selected
via the mode menu.
1. On the mode menu, Select
Switch FPGA
->
Time Domain FPGA
.
2. Click Yes on the confirmation message, to switch to the Time Domain FPGA and reboot the BDS Receiver. See
Figure 55
