GPIB OPERATION

ML24XXA NATIVE COMMANDS

NOTES

The GPIB command error and GPIB execution error are always enclosed within exclamation marks (!). If no errors have been produced since the last ERRLST was read, the ERRLST will end with '!!!'.

When read for the first time after startup, a sensor may be reported as not fitted even though it is. This is because the error condition of a sensor used in a channel configu- ration was recorded before the sensor initialization was completed.

If a sensor is not used in a channel configuration, it will be reported as Zeroed, although it may not have been. If the sensor is then used in a channel configuration, it’s zero status will be correctly reported.

GPIB SETUP

Syntax: FAST <state>

state: ON or OFF

Remarks: This command allows the system, for speed purposes, to send the present system readings directly to the output, with no buffering at all (obeying the rules sent earlier when talk addressed). GPIB 488.2 rules specify that data should only be given after a request. FAST mode allows data to be read without requesting it first (like the HP 437/8). The following conditions and restrictions apply:

a. REMOTE is written across the screen, and no screen updates are done. b. Sensor data for a single sensor only can be output from display channel 1, according to the following rules:

If the input configuration for display channel 1 is set to either OFF or EXT VOLTS, it is set to ‘A’ and sensor A data is output if a sensor is con- nected to input A.

If the input configuration for display channel 1 is set to a sensor combina- tion (A-B, A/B, etc.), the configuration is left as is but only the sensor A data is output.

If the input configuration of display channel 1 is set to ‘B’, sensor B data is output.

c. Output from display channel 2 is set to OFF. d. Output is in dB only.
