Giga-tronics 2508A - IEEE 488.2 Common Commands

IEEE 488.2 Common Commands
2500A Series Operation Manual, 34172 Revision C, March 2008
3.3 IEEE 488.2 Common Commands
The commands and queries in the following table are defined by IEEE 488.2. IEEE 488.2 defines how
the instrument should respond to the following common commands and queries. These commands are
independent of the SCPI and GT-12000 native command sets.
[SOURce]:PULSe:PERiod <pm_per> Sets the period of the internal pulse modulation generator to the
value specified by <pm_per>. (Not available with Option 17A or
17B). The default units are in Hertz unless otherwise specified.
[SOURce]:PULSe:SYNC <pm_sync> Sets the delay of the pulse modulation sync signal. The delay range
of the Pulse Sync Output function is 100 nSec. to 10 mSec. (Not
available with Option 17A or 17B) The default units are in Hertz
unless otherwise specified.
[SOURce]:PULSe:WIDTh <pm_width>
(S|MS|US)
Sets the internal pulse modulation width to the value specified by
<pm_width> (Not available with Option 17A or 17B).
[SOURce]:PULSe:WIDTh? Queries the internal pulse modulation width. The return value is in
seconds. (Not available with Option 17A or 17B).
Table 3-13: IEEE 488.2 Common Commands
Command Name Description
*CLS Clear Status Clears the event registers in all status groups. It also
clears the Event Status Register and the Error/Event
Queue
*ESE <ese> Standard Event Status Enable Sets the Standard Event Status Enable Register. A
service request is issued whenever the specified event
has occurred
Range of <ese>: 0 - 255
*ESE? Standard Event Status Enable Returns the value of the Standard Event Status Enable
Register. The value returned is a decimal value
representing the current state of the Standard Event
Status Enable Register
*ESR? Standard Event Status Register Returns the value of the Standard Event Status
Register. The value returned is a decimal value
representing the current state of the Standard Event
Status Register
*IDN? Identification Returns the instrument identification
*OPC Operation Complete Causes the Operation Complete bit (that is, Bit 0 of the
Standard Event Status Register) to be set to 1 when all
pending selected device operations have been finished.
List Mode only
*OPC? Operation Complete Places an ASCII character 1 into the device’s output
queue when all pending selected device operations
have been finished. Unlike the *OPC command, the
*OPC? query does not affect the OPC Event bit in the
Standard Event Status Register (ESR).
