GAIN0
Displays or sets the Gain0_0 and Gain0_1 outputs
Usage
GAIN0 <CR> or <LF> and GAIN0=n <CR> or <LF>
Operating Modes
Open
Description
The GAIN0 command displays or sets the Gain0_0 and Gain0_1 outputs. These are logic outputs
on the Option 1 connector; they correspond to Gain Control A and Gain Control B, respectively, for
Channel 1 as shown in Table 12.
NOTE.
The Gain0_0 and Gain0_1 outputs should be connected to +5 VDC through a 10-
Kohm resistor for standard TTL logic.
NOTE.
The Gain0_0 and Gain0_1 outputs are set only after the instrument is set into either
the Run or the Calibration operating mode.
There are four possible output setting combinations for Gain0_0 and Gain0_1 where an ON setting
corresponds to an output of 0 volts and an OFF setting to an output of +5 VDC:
Gain0=0: Gain0_0 = 0FF, Gain0_1 = OFF Gain0=1: Gain0_0 = ON, Gain0_1 =
OFF Gain0=2: Gain0_0 = OFF, Gain0_1 = ON Gain0=3: Gain0_0 = ON, Gain0_1 =
ON
NOTE.
The GAIN0 command must be followed by the ***E command to save the setting.
Returns
See Examples below.
Examples
Enter GAIN0 <CR> or <LF> The instrument displays the gain setting:
GAIN0 Gain0_0: ON Gain0_1: ON
Enter GAIN0=2 <CR> or <LF>
The instrument sets the Gain0_0 output to OFF (+5 VDC) and the Gain0_1 output to ON (0 volts)
for Channel 1.
