1.
STORAGE switch.
When set to ON, pro¬
vides display storage while new measure¬
ment is being made.
In OFF
position,
allows
continuous
display
of
counting
process.
2.
OSC INT-EXT switch.
In
INT
position,
selects
normal
counter
operation
using
internal time base.
In EXT position, per¬
mits use of external time base.
3.
OSC jack. With INT-EXT switch set to INT,
provides 10 MHz, >3 V p-p output (no load),
500 series impedance. With INT-EXT switch
set to EXT, allows use of external time base
from 100 Hz to 10 MHz at >1 volt rms (5 V
peak maximum).
4.
MARKER A and B jacks.
Provides marker
outputs to intensity modulate HP 180 Oscillo¬
scope.
Markers begin coincident with chan¬
nel trigger points.
5. GATE jack. Provides >2.4 volts output (open
circuit) for external use.
Has 500 series
impedance.
Output is low when counter's
main gate is open and high when gate is
closed.
6. TIME BASE OUTPUT jack.
Provides neg¬
ative going > +3 to 0 V pulses (open circuit),
>50 nanoseconds wide.
The line has a 500
series impedance.
In START, frequency out¬
put is CHANNEL A signal divided by MULTI¬
PLIER setting.
7.
AC LINE.
IEC type with offset pin con¬
nected to chassis.
8.
AC LINE FUSE.
1.50 A at 115 V, 800 mA
at 230 V.
9.
115/230 volt switch.
Insert narrow screw¬
driver
and
slide
switch to
show
desired
voltage.
10. DIGITAL RECORDER connector (Option 003
only).
50-pin connector for digital recorder
interconnection.
11. REMOTE
PROGRAM
connector.
Option
002:
36-pin connector to allow remote con¬
trol of counter modes and functions.
Option 004:
50-pin connector to allow re¬
mote control of all counter functions except
FAST /NORM.
