■

Queries event status register 0.

:HEADer

■

Enables and disables headers for the response messages.

:HEADer?

■

Queries whether or not headers on response messages are enabled.

 Syntax 

ESR0?

 Function 

Returns the value of event status register 0 (ESR0) as a numerical value in
NR1 format between 0 and 255, and then clears event status register 0.
No header is prefixed to the response message.

 Example 

Response

 

4

Bit 2 of ESR0 has been set to 1.

 Error 

If the response message is longer than 300 bytes, a query error is generated.

 Syntax 

:HEADer

_<data>

 <data> 

ON/OFF (character data)

 Function 

Sets whether or not the 3157 will prefix headers to its response messages.
When powering on, <data> is initially set to OFF.

 Example 

Transmission

 :HEADer ON

Headers are prefixed to response messages.
