Frequency Response Adjustment
This adjustment aims to obtain the actual frequency response characteristics
of the signal channel, thus to perform appropriate compensation. Since the
waveform amplitude will decrease as the input frequency increases, it is
essential to compensate for the amplitude to match it to the frequency. This
adjustment should be performed after the channel adjustment.
1. Turn on the generator and connect it to the PC using a USB cable.
2. Connecting the USB end of the Power Meter to the USB port of the PC,
upon which the Power Meter indicator light will be brightened. Only after the
indicator light goes out from red, should it be connected to the generator
output.
3. Run the script FrqRespCalib.py prepared previously. In approximately 10
seconds the prompt message will display on the screen to indicate the
operator to connect the Power Meter. After the generator completes the
adjustment for CH1, the prompt message displays on the screen will
prompt the operator to remove the BNC cable to CH2 to start adjustment.
4. After the two channel adjustment completed, please disconnect all the
connections.
