Equipment information:

Racal 1995 Counter
Model: 1995
Date: 1988
Category: Measurement instruments
Group: Counter
                                    The 1995/1996 system universal counter utilizes a
microprocessor-controlled multiple register data acquisition
IC for counting and timing to 200 MHz (1.3 GHz on the 1996
with Input C).
The counter provides the following measurement functions:
frequency, frequency ratio, period, 1-ns resolution time
interval, automatic pulse parameters (including duty cycle
and slew rate), phase, and totalize. Time interval averaging
is available via software-derived functions.
The frequency range on Inputs A and B is 0 to 200 MHz; 40
MHz to 1.3 GHz on Input C using an additional board. Trigger
levels on Inputs A and B can be set manually via the front
panel keypad or via auto-trigger with 50% trigger points.
The DC offset component of the input signal may be tracked
by auto-triggering in between readings in the manual mode
(peak tracking). , Use of a timing error correction (TEC)
technique permits measurements with 9-digit resolution m one
second and a single-shot time-interval resolution to 1 ns.
The counter is housed in a 3.5n high X 19" wide full-rack X
19" deep standard corporate enclosure. Total weight does not
exceed 22 lbs (10 kg). Unit is adaptable to rack or bench
top use.
