Programmable Bidirectional DC Power Supply 62000D Series
Operating and Programming Manual
5-10
Type: Device status
Description: Reset System
Syntax: *RST
Parameter: None
*SAV Save Command
Type: Device status
Description: This command stores the present state of the DC power supply and the
states of current mode in a specified location in memory.
Syntax: *SAV
Example: *SAV
*SRE Service Request Enable Command/Query
Type: Device status
Description: This command sets the condition of the Service Request Enable
register, which determines which events of the Status Byte register (see
*STB) are allowed to set the MSS (Master Status Summary) bit. A "1" in
the bit position enable bits are logically ORed to cause Bit 6 (the Master
Summary Status Bit) of the Status Byte register to be set. See Status
Byte register for detail description.
Syntax: *SRE <NRf>
Parameter: 0 to 255
Example: *SRE 20 Enable the CSUM and MAV bit of the Service Request.
Query Syntax: *SRE?
Return Parameter: <NR1>
Query Example: *SRE? Return the current setting of Service Request Enable.
*STB? Read Status Byte Query
Type: Device status
Description: This query reads the Status Byte register. Note that the MSS (Master
Summary Status) bit instead of RQS bit is returned in Bit 6. This bit
indicates if the High Slew Rate Load has at least one reason for
requesting service. *STB? does not clear the Status Byte register, which
is cleared only when subsequent action has cleared all its set bits.
Query Syntax: *STB?
Return Parameter: <NR1>
Query Example: *STB? Return the contents of Status Byte.
Return Example: 20
1. Status Byte Register:
The Status Byte Register is composed of eight bits that summarize
an overlaying status data structure. The Status Byte Register can
be read using *STB? to return a decimal expression of the register
contents (which means the total byte weight of all the byte set to
“1”.)
