2-2
inverting (–) input of the amplifier for operation as a differential
comparator or applied internally as a true differential offset
voltage. The voltage is also available to be used externally
through a rear panel connector.
To maintain the amplifier's high Common Mode Rejection
performance, special differential probes such as the LeCroy
model DXC series are recommended and are available as
optional accessories.
The DA1855A series is comprised of 2 models which differ in
physical configuration. Both contain the same 100 MHz
differential amplifier which provides high common mode rejection,
extremely fast overdrive recovery, selectable ÷1 or ÷10
attenuation, selectable X1 or X10 gain, a 5-1/2 digit Precision
Voltage Generator (PVG), selectable upper bandwidth limiting
filters, and effective gain display.and
limiting. The PVG is provides a calibrated reference for
Differential Offset or Comparison modes. The PVG reference
voltage is also available through a BNC connector on the rear
panel.
DA1855A: The DA1855A is a single channel unit packaged in a
convenient desk top housing.
DA1855A-PR2: Two independent model DA1855A amplifiers
packaged in one housing with one line power input connection.
The housing is intended for desk top use, where it can be placed
under an oscilloscope.
Rack mounted versions available for models:
DA1855A-RM: Single channel rack mounted version.
DA1855A-PR2-RM: Dual channel rack mounted version.
