8510XF Network Analyzer Systems 7-43
Menus & Commands
New GPIB Commands
New GPIB Commands
The table below lists the 8510C GPIB commands that have been added with
the 8510XF firmware.
Table 7-2 New GPIB Commands
COMMAND EQUIVALENT SOFTKEY FUNCTION
HIDECNFG [SYSTEM] {MORE} {SERVICE}
{XF TESTSET SERVICE} {HIDE
CONFIGURATION}
Hides the configuration display.
IFFREQ<freq> [SYSTEM] {MORE} {IF FREQ} Sets the IF frequency.
Under normal operation, the frequency is
fixed at 20 MHz; this command can be used
to modify the frequency for special
applications. The effective range of
modification is restricted by hardware
performance characteristics; typically, the
20 MHzIF canbeincreased ordecreasedby
about 10 kHz.
INPULGCFRQ<frequency part of correction
table>
No softkey equivalent Used by Agilent service engineers to load
values into the frequency part of the
correction table in the memory of the 8510C.
INPULGCPWR<power part of correction
table>
No softkey equivalent Used by Agilent service engineers to load
values into the power part of the correction
table in the memory of the 8510C.
LGCATTSET<att> [SYSTEM] {MORE} {SERVICE}
{XF TESTSET SERVICE} {LEVELING
SETTINGS} {SET ATTN}
Used by Agilent service engineers to set the
attenuator in the programmable gain portion
of the level controlcircuit. Values range from
0 to 133; LSB = 0.5 dB.
LGCCALGAIN [SYSTEM] {MORE} {RF POWER CONFIG}
{MORE} {RESET DET GAIN CAL} {RUN
CAL NO PRESET}
Runs the detector gain calibration routine
(without presetting the system afterwards).
LGCDACSET<dac> [SYSTEM] {MORE} {SERVICE}
{XF TESTSET SERVICE} {LEVELING
SETTINGS} {SET DAC}
Used by Agilent service engineers to set the
multiplying DAC in the programmable gain
portion of the level control circuit. Values
range from 0 to 255.
LGCGAINSET<iflevel-dB> [SYSTEM] {MORE} {SERVICE}
{XF TESTSET SERVICE} {LEVELING
SETTINGS} {SET GAIN}
Used by Agilent service engineers to set the
relativeIF level,by settingtheattenuator and
DACin theprogrammablegain portion ofthe
RF level control circuit. Detector gain
calibrationmustbe donefirst,in orderforthis
function to work.
