? Displays available commands.
ver Displays information about hardware version, firmware version, and
firmware release date.
freq
Displays selected frequency information in the following format in
kHz:
Start Freq - selected sweep start frequency
End Freq - selected sweep end frequency
Span - selected span
Min - minimum allowed frequency
Max - maximum allowed frequency
sweepu Displays information in the following format about the selected
frequency in
kHz:
Start Freq - selected sweep start frequency
End Freq - selected sweep end frequency
Freq step - selected frequency step
sweepu
<start frequency in kHz>
<end frequency in kHz>
<frequency step in kHz>
kHz
Sweeps entered spectrum range with specific step once and returns
the detected values in dBm. Enter values in
kHz :
Start Freq - selected sweepu start frequency
End Freq - selected sweepu end frequency
Freq step - selected frequency step
- Each sweep starts after a ‘#’ character
- Tracepoints are returned as hexadecimal unsigned byte strings
consisting of 2 characters (except when overload is detected
–
then ‘^’ character is returned also)
- The frequency step depends on the currently selected RBW
(values in
Table 1 )
- The minimum allowed span (i.e. difference between the start
and end frequencies) depends on the currently selected RBW .
Choose RBW values from Table 1
- If there is external attenuation used it must be added (as
“offset”) to obta in the actual power value.
- To stop the data stream, send any character (but the sweep will
continue on the device, see “ stop ”)
