GPIB Operation Functional Groups
ML2437A/38A OM/PM PN: 10585-00001 Rev. P 8-9
8-7 Functional Groups
Throughout the ML24XXA (native) mode section of this chapter, the distinctive, white on
black text, in the upper corner of each command description area, indicates the Functional
Group to which the command belongs (Figure 6-1). All ML24XXA (native) commands are
presented by Functional Group in Appendix C, GPIB Quick Reference.
The Functional Groups are:
BNC
Commands in this group are used to configure the rear panel BNC inputs and outputs.
Calibration
The CALIBRATION group commands are used for the 0.0 dBm reference calibration and
zeroing of the power sensors.
Channel
The CHANNEL command group controls the configuration of the two channels. When both
channels are activated, Channel 1 appears at the top of the display and Channel 2 at the
bottom. If one channel is turned off, the remaining channel appears in the centre of the
screen.
Data Output
Commands in this function group are used to place data on the GPIB to be read by the
controller.
Display
These commands control characteristics of the display, including the peakmeter reading
display and contrast adjustments.
GPIB 488.2
This group contains the GPIB 488.2 mandatory commands. Refer to the IEEE 488.2-1987
Standards documents for further information.
GPIB Setup
The commands in this group control the GPIB Address, GPIB command set emulation mode
(ML24XXA, ML4803A or HP Emulation), and other parameters.
GPIB Trigger
Commands in this group are used to configure GPIB triggering and setup the GPIB Group
Execute Trigger (GET) and TR commands (TR0, TR1, TR2, TR3). Note that these commands
are exclusive to GPIB, and do not have equivalent front panel operations.
