*RF<cr> Read Input signal levels command.
The *RF command returns a string with the signal levels for INPUT 1 and INPUT 2 in dBm
units. The signal levels are approximate and the accuracy is +/- 1 dB in the range of –
10dBm to +15 dBm.
For example:
input: *RF<cr>
output:RF1:13.09, RF2:10.20<cr>
*PWR<cr> Read the internal voltage levels of the instrument command.
The *PWR command returns a string with the internal voltage levels of the instrument and
may be used to monitor both the power supply derived from the AC mains as well as the
power from the DC battery backup system. Used to read the internal voltage levels. The
DC values will not be present unless the DC backup power is supplied to the instrument.
Normal values are in the range of 13.8 - 14.8V.
