CAL_WBGAIN
Description Overlapped long-term command, ignored if not in remote.
Does Wideband AC Module (Option 5700-03) gain calibration. There are two different
calibration procedures for the wideband module: gain and flatness. Wideband gain is to be
done at every calibration cycle. Wideband flatness is needed only during full verification
(recommended every two years). For reference, the manual procedure for wideband gain
cal is in Chapter 7.
To calibrate wideband gain in remote, the wideband output cable must be connected to the
calibrator’s SENSE binding posts as described in Chapter 7, then the controller must send
commands in the same sequence as in the example. For positive gain, the center conductor
is connected to SENSE HI. For negative gain, the center conductor is connected to SENSE
LO.
Parameter
PGAIN (Calibrates wideband positive gain)
NGAIN (Calibrates wideband negative gain)
STORE (Stores wideband constants into EEPROM)
Example: CAL_TEMP 23.5
CAL_WBGAIN PGAIN (Calibrates positive gain)
(Reverse the SENSE connection now)
CAL_WBGAIN NGAIN (Calibrates negative gain)
CAL_WBGAIN STORE
CAL_ZERO
Description Overlapped long-term command, ignored if not in remote.
Performs internal zeros calibration. This removes offsets on the 2.2V dc range. It takes
about 2-1/2 minutes, plus 30 seconds if teamed with 5725A, and does not require setting
the CALIBRATION switch.
Parameter None
CLOCK
Description Sequential command, ignored if not in remote.
Sets the clock/calendar. The rear panel CALIBRATION switch must be in the ENABLE
position or an execution fault results.
Parameters:
1. Time in 24-hour format as HHMMSS
2. Date as MMDDYY, DDMMYY, or YYMMDD depending on the setting the DATEFMT.
Examples
CLOCK 133700, 071788 (Sets the clock/calendar to 1:37 p.m., July 17, 1988.)
CLOCK 080000, 101088 (Sets the clock/calendar to 8:00 a.m., November 10, 1988.)
CLOCK?
Description Sequential command.
Returns the setting of the clock/calendar.
Parameter None
Response
1. (Integer) Time in 24-hour format as HHMMSS.
2. (Integer) Date as MMDDYY, DDMMYY, or YYMMDD depending on the setting of
DATEFMT.
Example: CLOCK?
Returns:
"150000,090188" if the clock/calendar is set to 3 p.m., September 1, 1988.
