To set the Start Frequency

c460-00:~ # echo “MTA LISTEN 18 DATA ‘FA 100MZ’”| cat -> /dev/gpib0

or shortcut as:

c460-00:~ # echo “SEND 18 ‘FA 100MZ’”| cat - > /dev/gpib0

FA is a Spectrum Analyser command used to set the Start Frequency. In this case, the Start

Frequency is set to 100 MHz.

To set the Stop Frequency

c460-00:~ # echo “MTA LISTEN 18 DATA ‘FB 300MZ’”| cat -> /dev/gpib0

or shortcut as:

c460-00:~ # echo “SEND 18 ‘FB 300MZ’”| cat - > /dev/gpib0

FB is a Spectrum Analyser command used to set the Stop Frequency. In this case, the Stop

Frequency is set to 300 MHz.

To set the Zero Span mode

c460-00:~ # echo “MTA LISTEN 18 DATA ‘SP 0HZ’”| cat -> /dev/gpib0

or shortcut as:

c460-00:~ # echo “SEND 18 ‘SP 0HZ’”| cat - > /dev/gpib0

SP is a Spectrum Analyser command used to Changes the total displayed frequency range

symmetrically about the center frequency. Specifying 0 Hz enables zero-span mode, which

configures the spectrum analyzer as a fixed-tuned receiver.

To get the Spectrum Analyser model number

c460-00:~ # echo “MTA LISTEN 18 DATA ‘ID?’”| cat -> /dev/gpib0

or shortcut as:

c460-00:~ # echo “SEND 18 ‘ID?’”| cat - > /dev/gpib0
