1.
"A" Commands — The maximum number of characters for the A1 command string is
12. The A2 and A3 commands are not supported.
2.
"C" Commands — Calibration commands are not supported by the 182 language. You
must use the SCPI language to calibrate the Model 2182 over the bus.
3.
"G" Commands — The G4 through G7 commands are not supported by the 182
language. The Model 182 does not use time stamp.
4.
"H" Commands — The H1 command is not supported by the 182 language.
5.
"I" Commands — The minimum buffer size for the Model 2182 is 2, while the
minimum buffer size for the Model 182 is 1. Therefore, to set minimum buffer size, I1,0
is valid for the Model 182 and I1,2 is valid for the Model 2182. The I2 command
(circular buffer) is not supported.
6.
"J" Commands — For the Model 2182, J1 uses the last reading as the Rel value
(whereas, the J1 command for the Model 182 uses the next reading as the Rel value). The
J3 command simply enables analog output relative and uses the present Rel value.
7.
"S" Commands — The S3 command has been added to include a 1 second integration
period.
8.
"T" Commands — The front panel TRIG key is always operational, even when T10X
is sent to disable all triggers.

"U" Commands:
U1 - For the Model 2182, the U1 error status word only supports the IDDC (Invalid
Device-Dependent Command) error (bit 0), the IDDCO (Invalid Device-Dependent
Command Option) error (bit 2), and the Uncalibrated Error (bit 8). All other bits
remain at zero.
U2 - The Model 2182 uses two processors, while the Model 182 uses three
processors. Therefore, the U2 command will be formatted to only provide revision
levels for the Front Panel Processor and the Main Processor.

11.
"V" Commands — The V1 command is not supported.
12.
"Z" Commands — For the Model 2182, Z1 uses the last reading as the Rel value
(whereas, the Z1 command for the Model 182 uses the next reading as the Rel value).
The Z3 command simply enables reading relative and uses the present Rel value.
