CHARACTERISTICS
The Type 184 is a compact, precision-built instrument
capable of producing accu rate time markers for appl ica­
tions in the laboratory, production line or field. Sixteen time­
marker selections and five sine-wave marker interva ls provide
time-marker selections from 2 nanoseconds to 5 seconds.
Seven trigger pulse selections provide a triggering pulse
rate from 1
fLS
to 5 s.
All outputs of the Type 184 are frequency controlled by
a stable 1 0 MHz crystal oscillator.
Operating Data
Marker Output
Provides positive time marks of 1 volt minimum amplitude
(into 50 0). Marker periods are established by pushbutton
MARKER SELECTOR switches.
Marker Periods
Sinusoidal
10, 20 and 50 ns (H.F. SELECTOR must be off for 10 ns
markers).
Periodic Pulses
.1 , .5, 1 , 5, 10, 50
fLS
.1, .5, 1 , 5, 10, 50 ms
. 1, .5, 1, 5 s
HF Output
Provides 2 ns or 5 ns sine-wave markers of 0.3 V minimum
ampl itude (into 50 0).
Marker Amplifier Output
Provides positive or negative time marks of 25 V minimum
amplitude (into 1 kO). Marker intervals from 1
fLS
to 5 s estab­
lished by the pushbutton MARKER SELECTOR switches.
Trigger Output
Provides positive triggers of >0.4 V into 50 0 or >2.5 V
into open circuit. Period established by pushbutto; Trig-

ger Selector switches. Trigger periods are: 1 and 1 0
fLS;
.1, 1 and 1 0 ms; .1 and 1 s.
