COMMAND SUMMARY
positions to the bandwidth, < 20 Hz and > 100 but any
numeric is accepted. The value is compared to 1 and the correct
position is determined (> 1 sets the position to 100 and
1 sets the position to 20 Hz). After the value is 100
l suffix]
l
FM:INTernal:FREQuency?
Sets and queries the frequency (in Hz) of the internal FM source.
After the value is 1 MHz.
l
FM:INTernal:FUNCtion
l
FM:INTernal:FUNCtion?
Sets and queries the waveform of the internal FM source.
After the value is
l
l FM:SOURce?
Sets and queries the source of the FM modulating signal.
After the value is
l FM:SENSitivity suffix/V]
l
FM:SENSitivity?
Sets and queries the FM Input sensitivity.
The *RST value is MAX (10 MHz/V) .
l
FM:STATe
l
FM:STATe?
Sets and queries the FM modulation state.
After the value is OFF.
Frequency Subsystem Any two frequency setting headers STOP, or
SPAN) may be sent in a single message and the resulting sweep
is what was requested. The order of the headers in the message
does not make any difference in the final result. When a message is
completed, coupling equations are used to fix the unset parameters to
the
correct values. These equations specify that:
center frequency = (start + stop) 2
frequency span = (stop start)
If more than two are sent then the last two in the message are used
to determine the sweep and no errors are given.
If only one header is sent in a message, then the assumed pairs are
center/span and start/stop. In other words, if only center is sent,
then span is kept constant (if possible) while adjusting center to the
requested value. The start/stop frequencies are updated to reflect the
changes based on the coupling equations.
