Model 800A3B
Rev D 21
2.6.6.6 IO Board Firmware Revision
Query to get the firmware revision of the I/O Board.
Syntax:
*IOB?
Parameters: None
Query only (always requires a ? character)
Response Format: INTERFACE_BOARD_SW_REVx<LF>
Where:
x = firmware revision
Example: To get the firmware rev. of the I/O Board, send the following command:
*IOB?<LF>
Response: INTERFACE_BOARD_SW_REV3.00<LF>
2.6.6.7 Machine State
This query reads the RF gain, detector gain, ALC threshold, and ALC response time of the amplifier.
Syntax: MSB?
Parameters: None
Query only (always requires a ? character)
Response Format: RF<space>GAIN=x,
DT<space>GAIN=x,
THRES=x,
RESP=y<LF>
Value(x):
For RF Gain, Detector Gain*, and ALC Threshold*:
0 = Minimum
100 = Maximum
Value(y):
For Response Time*:
0
= Minimum
7
= Maximum
Example: To get the machine state, send the following command:
MSB?<LF>
Response:
RF<space>GAIN=100,DT<space>GAIN= 50,THRES= 75,RESP=1 <LF>
(RF gain is 100%, Detector Gain* is 50%, ALC Threshold* is 75%, and ALC Response
Time* is set to 5mS) *The values displayed have no relevance since these features are not
supported for this amplifier.
