Figure 1: Configuration Jumper for Scale Factor Coding
Because the line that carries the scale factor coding is disabled, see the chart on
page 8 to correctly interpret the volts/division setting of the oscilloscope.
Connecting the TEKPROBE Output. To engage the TEKPROBE output, align the
fin on the output head counterclockwise with the clearance on the oscilloscope
connector. Push the connector in and and lock the fin clockwise.
Use the 1103 TEKPROBE Power Supply to connect the ADA400A Differential
Preamplifier to any oscilloscope that does not provide TEKPROBE power. The
1103 TEKPROBE Power Supply has connections for two probe channels.
NOTE. Use the offset controls of the ADA400A Differential Preamplifier to adjust
the offset level. The offset controls on the 1103 TEKPROBE Power Supply do not
operate with the ADA400A Differential Preamplifier.
Because the 1103 TEKPROBE Power Supply does not connect the line that
carries the scale factor coding, see the chart on page 8 to correctly interpret the
volts/division setting of the oscilloscope.
For more information about using the 1103 TEKPROBE Power Supply, refer to
the instruction manual that comes with the power supply.
Always set the input impedance of the oscilloscope to 1 MQ and the input
coupling of the oscilloscope to DC. Setting the impedance to 50 Q loads
