MAV 

Message Available Bit 4 (16) 
Indicates that at least one reply message is waiting in the RPM4 IEEE-488 output 
queue. 

ERROR 

Error Queue Not Empty Bit 2 (4) 
Indicates that at least one command error message is waiting in the RPM4 IEEE-488 
error message queue.  Use the “ERR?” query to get this message. 

RSR 

Ready Summary Bit 0 (1) 
Indicates that an enabled bit in the Ready Status Register became set. 

The RPM4 contains an 8 bit Standard event register that reflects specific RPM4 events.  
Enabled events in this register will set or clear the ESB bit of the Status Byte Register. 

Table 17.  8 bit standard event register 

(128) 

(64) 

(32) 

(16) 

(8) 

(4) 

(2) 

(1) 

 

This register can be read using the “*ESR?” query, Each of these status bits can set the ESB 
bit of the Status Byte Register, causing a SRQ to occur IF the ESB bit is enabled to do so.  
The Standard Event Status Enable Register (“*ESE” program message ) determines which of 
these flags are able to assert the ESB bit.  The description of these bits are given as: 

Power On Bit 7 (128) 

Indicates that the RPM4 power has been cycled since the last time this bit was 
read or cleared. 

URQ 

User Request Bit 6 (64) 

Indicates that the RPM4 was set to local operation manually from the front panel 
by the user (pressing the [ESC] key). 

Command Error Bit 5 (32) 

Indicates that a remote command error has occurred.  A command error is 
typically a syntax error in the use of a correct program message. 

Execution Error Bit 4 (16) 

Indicates if a remote program message cannot be processed due to device 
related condition. 

DDE 

Device Dependent Error Bit 3 (8) 

Indicates that an internal error has occurred in the RPM4 such as a transducer time-
out. 

QYE 

Query Error Bit 2 (4) 

Indicates that an error has occurred in the protocol for program message 
communications.  This is typically caused by a program message being sent to 
the RPM4 without reading a waiting reply. 

Request Control Bit 1 (2) 

This bit is not supported as the RPM4 cannot become the active controller in charge. 

Operation Complete Bit 0 (1) 

Indicates that the RPM4 has completed all requested functions.
