RC###
ReCall operating parameters from memory channel.
###
represents the
three digits of the memory channel from which to recall the parameters.
Recalled data is entered immediately. This command is also used to set
the starting channel for a scan or sweep operation in which case it is
followed by a Scan or Sweep command. (Range: 0 through 249)
RSccc,ffff
ffff,ddd
Special Recall command, performs a recall of the channel number
specified by the number ccc. In addition, the frequency from the recalled
channel is ignored, and the frequency is set to the value ffffffff. The
current AGC value is dumped to the preset value ddd. When this
command is executed, the display is not updated, and will continue to
show the previous settings. Units and limits for the three parameters are
the same as for the RC###, F12345678, and DP123 commands. Note: the
dump parameter is given in units of dB, not 1/2 dB as other commands
use. Leading zeros may be omitted from each argument field to reduce
communication time.
S*?
1
Request receiver meter reading. Replace the
*
with an
S
to request signal
strength, an
A
to request audio output level, and an
F
to request
frequency error. The value returned will be for the currently selected ISB
Access Mode. Frequency error may only be requested when receiver
operating mode is not ISB.
SA?
SA±123
Request audio output level: The
±
character represents the sign of the
value and will be or -. Digits 1 through 3 represent the significant
digits of the audio output level in dB below one milliwatt in units of 1/10
dBm. The 1 represents the 10s of dB, the 2 represents the 1s of dB, and 3
represents the 1/10s of dB (Range: -50.1 t12).
SC###
Begin SCan of memory channels.
###
represents the three digits of the
highest memory channel to be scanned. The scan begins at the memory
channel most recently recalled with the
RC###
command. (Range: 0
through 249)
SF?
SF±12345
Request frequency tuning error: The
±
character represents the sign of
the value and will be or -. Digits 1 through 5 represent the
significant digits of the frequency error in Hertz where 1 represents the 10
kHz digit and 5 represents the 1 Hz digit. (Range: bandwidth dependent).
SG?
SGbbbbbbbb
Request status of last GPIB Service Request: Each
b
character is
replaced with a 0 to indicate that the corresponding bit was not the
reason for the last SRQ, or a 1 to indicate that the corresponding bit was
responsible for the last SRQ. See figure 3-11 for Serial Poll response byte
bit positions.
