GAIN1
Displays or sets the Gain1_0 and Gain1_1 outputs
Usage
GAIN1 <CR> or <LF> and GAIN1=n <CR> or <LF>
Operating Modes
Open
Description
The GAIN1 command displays or sets the Gain1_0 and Gain1_1 outputs. These are logic outputs on
the Option 1 connector; they correspond to Gain Control A and Gain Control B, respectively, for
Channel 2 as shown in Table 12.
NOTE.
The Gain1_0 and Gain1_1 outputs should be connected to +5 VDC through a 10-
Kohm resistor for standard TTL logic.
NOTE.
The Gain1_0 and Gain1_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 Gain1_0 and Gain1_1 where an ON setting
corresponds to an output of 0 volts and a OFF setting to an output of +5 VDC:
Gain1=0: Gain1_0 = 0FF, Gain1_1 = OFF Gain1=1: Gain1_0 = ON, Gain1_1 = OFF Gain1=2:
Gain1_0 = OFF, Gain1_1 = ON Gain1=3: Gain1_0 = ON, Gain1_1 = ON
NOTE.
The GAIN1 command must be followed by the ***E command to save the setting.
Returns
See Examples below.
Examples
Enter GAIN1 <CR> or <LF> The instrument displays the gain setting:
GAIN1 Gain1_0: ON Gain1_1: ON
Enter GAIN1=2 <CR> or <LF>
The instrument sets the Gain1_0 output to OFF (+5 VDC) and the Gain1_1 output to ON (0 volts)
for Channel 2.
