Controls
Range FS Volts Switch Selects 1 V or 10 V FS Input Range.
Meter Input Switch Selects WB, NB amplitude, or PH (phase).
DC Output TC Switch
Selects SLOW or FAST time constant for
meter (and DC outputs).
Manual Auto (Limit) Switch Selects Auto BW or Manual BW. In Auto
(Limit) mode, Bandwidth is 10% of the REF
frequency.
In the MANUAL mode, a fixed bandwidth is
selected via the front panel BW Hz thumb
switch.
Filter IN-OUT Switch Located on the front panel of the chassis,
allows the signal to pass through the
tracking filter in the Filter position and to
bypass the tracking filter in the Bypass
position.
Indicators
Level Meter 3-1/2 Digit meter indicating level in Volts
RMS or Degrees.
OVERLOAD LED LED illuminates if input to tracking filter is
too high for selected range, or if output
from filter to meter is too high.
ERROR LED LED illuminates when an in-correct signal is
applied to the REF Input.
