PREAMPLIFIER GAIN
The default gain of the preamplifier is 20 dB, 14 dB is achieved
with 0 Ω resistors in the R11and R12 positions. The 14 dB and
20 dB preset gains are accurate because of the close matching of
the internal thin film resistors. The gain accuracy after installing
external resistors is subject to inherent tolerance of absolute
accuracy; however, any pair of preamplifiers is reasonably
matched when standard 1% SM resistors are used.
OUTPUTS
The DSX outputs are available on the OUT1 and OUT2 SMA
connectors and are series terminated with decoupling capacitors
and 49.9 Ω series resistors.
DC OPERATING CONDITIONS
Table 4 lists the trimmers and their functions provided for
convenient dc level adjustments of gain, reference voltage, and
output common-mode voltage. Table 5 lists the switches and
their functions.

Switch
Function
VG1IN
Connects –DSX1 to the SMA connector VGA1IN or to ground.
VG1+IN
Connects +DSX1 (ac-coupled) to the preamplifier output of Channel 1 (PAO1) or to the SMA connector VGA1+ IN.
CH1
Enables/disables Channel 1 preamp by connecting COM1 to ground (enable) or to +5V (disable).
CH2
Enables/disables Channel 2 preamp by connecting COM2 to ground (enable) or to +5V (disable).
VG2+IN_SW
Connects the +DSX input to the SMA VGA2+IN, the Channel 2 preamplifier output (PAO2), or the output of Channel 1 for
a cascade connection.
VG2IN
Connects –DSX2 to SMA VGA2IN or to ground.
GN1
Connects the VGN1 input to trimmer GN1_ADJ gain adjust wiper or leaves the input unconnected.
REF
Connects the reference input to the VREF_ADJ trimmer or leaves the input connected.
OCMV
Connects VOCM to the common-mode voltage trimmer, VOCM_ADJ.
