Models 176 & 178 DC Differential Amplifiers
Mounting Kits
Operation with Mounting Kit
When the Model 176 is mounted on a Model MK276 Mounting
Kit, all necessary gain setting and offset adjustments are
provided. A schematic and outline are shown in Figure 10.
Gain can be set in several different ways. For committed gain
applications, a fixed resistor may be soldered to the two
terminals on the PC board. By jumpering pin L to M and pin
S to N, gain may be adjusted from approximately 200 to 1000
with the fine gain adjust trimpot. By jumpering L to M, N to P
and R to S, the gain may be adjusted with the fine and coarse
adjust trimpots with a total gain range of about 30 to 1000. The
low gain range from 10 to 30 is best accommodated by
connecting a fixed resistor (10 kohms to 50 kohms) or
external pot in series with the coarse gain pot.
For convenience during system checkout or troubleshooting,
four testpoints are provided on the PC board which give
access to both terminals and the amplifier output. They are
located at the end of the board so that voltmeter or scope
probes may be inserted even if a number of cards are stacked
in a row.
The MK278 mounting kit has both fine and coarse gain
adjustment pot. The fine gain adjustment pot can be used
alone or for high gains (170 to 1000). Just connect pin L to pin
M and pin N to pin S on the mounting kit. For mid-range gains
(10 to 190), connect both pots in series between pins L and
S. The low gain range is best accommodated by connecting
a fixed resistor or external pot in series with the coarse gain
pot. Also, the mounting kit has terminals on the PC board for
connecting a fixed resistor. If necessary, the gain setting
resistance may be located off the PC board, but this may
degrade frequency response and increase the noise level.
The output offset adjustment has a range of ±7.5 mV.
