8845A/8846A
Programmers Manual
The second digit, which can vary from 1 to 6, indicates what measurement range the
Meter is in regardless of whether the Meter is in autorange or manual range.
The output string from a G0 command is acceptable as an argument for an "N" command.
This allows you to configure the Meter from the front panel and then record the
configuration over the bus for future use with a P0 command.
G1 (Get SRQ Mask)
The G1 command copies the present SRQ mask into the output buffer in the format
shown in Figure 7. The SRQ mask values are explained in Table 30. An example output
string follows. For more information about the SRQ mask, see the "Status Data" section
later in this section.
Example
33 CR LF
G3 (Get User-Defined Message)
The G3 command loads the output buffer with the indentification string and calibration
date of the Meter.
Example
FL8842A 10-8-2008 CR LF
G4 (Get Calibration Status)
The command loads the output buffer with the instrument's calibration status in the
format shown in Figure 7. The status is represented by a four-digit integer which is
interpreted in Table 30.
The first two digits are always 1 and 0. The third digit indicates whether or not the
calibration verification mode is enabled. The fourth digit indicates whether or not the
calibration mode is enabled. Since the Meter can only be calibrated in 8845A/8846A
mode, the response to the G4 command in the 8842A emulation mode will always be
1000.
Example
1000 CR LF
G5 (Get IAB Status)
The G5 command loads the output buffer with the IAB status in the format shown in
Figure 7. As Table 30 explains, the IAB status is a four-character string which indicates
the status of the FRONT/REAR switch (front or rear analog inputs selected), the
autorange feature (autorange on or off), and the OFFSET feature (OFFSET on or off).
The first digit is always 1. An example output string follows.
82
4: R4 (200 kΩ range)
1: S1 (Medium reading rate)
0: T0 (Continuous trigger)
Explanation
