Save Command
Syntax
*SAV<space><numeric value> where 1 ≤ <numeric value> ≤ 9
Function
Stores the current state of the attenuator in local memory; as many as nine
states can be stored. For each state, the following settings are stored:
• Total attenuation
• Display offset
• Wavelength
• LCM state (ON or OFF)
• Absolute power mode (ON or OFF)
• Beam block state at power-on (OFF or LAST)
• Beam block state (ON or OFF)
Example
*SAV 3
Service Request Enable Command
Syntax
*SRE<space><numeric value> where 0 ≤ <numeric value> ≤ 255
Function
Sets the bits in the service request enable register. The numeric value is
rounded to the nearest integer and converted to a binary number. The bits of the
register are set to match the bit values of the binary number.
Example
*SRE 216 sets the service request enable register bits to 11011000.
Service Request Enable Query
Syntax
*SRE?
Function
Returns the contents of the service request enable register as an integer that,
when converted to a binary number, represents the bit values of the register
Example
*SRE? returns 195 if the service request enable register is set to 11000011.
Read Status Byte Query
Syntax
*STB?
Function
Returns the contents of the status byte register as an integer that, when
converted to a binary number, represents the bit values of the register The bit
value for bit 6 of the register is the MSS bit value, not the RQS bit value.
Example
*STB? returns 170 if the status byte register is set to 10101010.
Self-Test Query
Syntax
*TST?
Function
Initiates a self-test of the attenuator, and returns 0 if the attenuator passes the
self-test or 1 if it fails.
Example
*TST?
