510 Output overload

"Trigger rate short" means that the period of the waveform is larger than the value of the

internal trigger rate. Thus not every trigger will generate a cycle (or burst) of the waveform.

4.8 COMMON COMMANDS

4.8.1 System Data Commands

*IDN? - Identification query

The identification query enables unique identification of the device over the GPIB. This query

should always be the last in a program message. It returns a string with four fields:

Manufacturer name

Model name

Serial number (0 if not relevant)

Version number

Command

Type: Common Query

Syntax: *IDN?

Response: BK, MODEL 4040B,0,V1.1

4.8.2 Internal Operation Commands

*RST - Reset command

The Reset command performs a device reset. It causes the device to return to the

factory default power up state.

Type: Common Command

Syntax: *RST

4.8.3 Device Trigger Commands

a) *TRG - Trigger command

This command is analogous to the IEEE 488.1 Group Execute Trigger interface message, and

has the same effect. It is used to trigger the device to output a wave, and is accepted only

when the trigger mode is set to Trigger, Gate or Burst, and the trigger source is set to BUS.

Type: Common Command

Syntax: *TRG
