Commands

The subsequent text is an alphabetical listing of all Calibrator commands and queries.
Common commands and device-dependent commands are shown as part of the listing.
Each command title includes a graphic that shows remote interface applicability, IEEE-
488 and RS-232, and command group: Sequential, Overlapped, and Coupled.
IEEE-488 (GPIB) and RS-232 Applicability
command and query has a check box that shows applicability to IEEE-488 (general
purpose interface bus, or GPIB) and RS-232 remote operations. For sorting, this list
ignores the * character that comes before the common commands.
Sequential Commands
occur in the data stream are named sequential commands. For more, see "Sequential
Commands" in Chapter 5.
Overlapped Commands
is necessary. These commands are named overlapped commands because they can
overlap the subsequent command before they complete execution. To be sure an
overlapped command is not interrupted during execution, use the *OPC, *OPC?, and
*WAI commands to find when the command is complete. For more, see "Overlapped
Commands" in Chapter 5.
Coupled Commands
(examples: CUR_POST and OUT) because they "couple" in a compound command
sequence. Precautions are necessary to make sure the action of one command does not
disable the action of a second command and cause a fault. For more information, see
"Coupled Commands" in Chapter 5.
CFREQ?
(Capacitance Frequency query) Shows the optimal frequency for stimulus when you
measure or calibrate capacitance output.
Response:
Example:
Shows 100 Hz as the optimal frequency for the selected capacitance output (1.0 μF for
this example). The indication is 0 if not sourcing capacitance.
CLOCK
(Real-Time Clock command) Sets the real time clock, time only, or date and time. To set
the date, the CALIBRATION switch must be in the ENABLE position.
Parameters: 1. (optional) year in the format YYYY

6-10
