S -14 -C COMPUTER POCKETSCOPE is a portable oscilloscope, especially designed for
computers and business machine service. Lightweight and small size together with simplicity of operation makes
this instrument IDEAL for field servicing. In addition ... signal amplifier with 0.35µs pulse rise from dc, with
signals of 1 mv observable...calibrated fixed sweeps and continuously adjustable linear time base from 20µs
to 2 seconds ... 5x stable time base expansion with complete parading for accurate pulse position ... sync
limiting...special intensification circuits permits observation of pulses shorter than 10µs at repetition rates
slower than 1 pps ... accessory attenuating and amplifying probes ... make this instrument a MUST for computer
type service.
S -4 -C SAR PULSESCOPES are improved JANized equivalents to the Gov't Model AN /USM -25.
These portable instruments (only 31.5 lbs. each) are for precision pulse time measurements in radar, TV and all
electronics equipment. Portray all attributes of the pulse ... internal crystal controlled markers of 10 and 50µs
available for self-calibration ...i n R operation a small segment of the A sweep is expandable for detailed observation
with a direct -reading calibrated dial accurate to 0.1 %. Video amplifier band -pass up to 11 me ... optional
video delay 0.55 us ... pulse rise time better than 0.05 As ... R pedestal (sweep) 2.4 to 24µs ... video sensitivity
of 0.1 v rms /in. Easily convertible tromps to yards. Operates from 50 to 400 cycles at 115 volts.
S -5 -C LAB PULSESCOPES are JANized equivalents to the Gov't Model AN /USM -24C. These
portable, AC, wide band -pass laboratory oscilloscopes are ideal for pulse as well as general purpose measurements.
Internal delay of 0.55 us permits observation of pulse leading edge. Includes precision amplitude calibration, 10X
sweep expansion, internal trace intensity time markers, internal trigger generators and many other features.
Video amplifier .06 v RMS /inch ... pulse rise time of 0.07 us or response to 11 me ... 5 to 50,000 us /in. triggered
or repetitive sweep ... internally generated markers from 0.2 to 500 us ... trigger generator from 50 to 5000 pps.
for internal and external triggering. Operates from 50 to 400 cycles at 115 volts AC.

S-14-6
S -11 -A INDUSTRIAL POCKETSCOPE is a small, compact, and lightweight instrument
for observing electrical circuit phenomena. The flexibility of the POCKETSCOPE permits its use for ac measurements
as well as for dc. The vertical and horizontal amplifiers are capable of reproducing within -2 db from dc to
200 kc with a sensitivity of 0.1 v rms /in...repetitive time base from 3 cycles to 50 kc continuously variable
throughout its range ... variations of input impedance, line voltage or controls do not "bounce" the signal -the
scope stabilizes immediately.
S-1 4-A HI -GAIN POCKETSCOPE provides the optimum in oscilloscope flexibility for
analysis of low -level electrical impulses. Vertical and horizontal channels: 10 mv rms /inch with response within
-2 db from dc to 200 kc and pulse rise of 1.8ps... non -frequency discriminating attenuators and gain controls
with internal calibration of trace amplitude ... repetitive or trigger time base with linearization from %z cycle
to 50 kc with ±sync or trigger.
t
S-1 4-B WIDE BAND POCKETSCOPE is ideal for investigations of transient signals,
dc signals, aperi odic pulses or recurrent waveforms. Vertical channel: 50 mv rms /in. within -2 db from dc to 700
kc ... pulse rise time of 0.35 As. Horizontal channel: 0.15 v rms /in. within -2 db from dc to 200 kc... pulse
rise of 1.84. Attenuators and gain controls are non -frequency discriminating ... trace amplitude calibration ...
repetitive or triggered time base from '/2 cycle to 50 kc ... ±sync or trigger ... trace expansion, filter graph
screen and many other features.
S-15-A
S -15 -A POCKETSCOPE is a portable, twin tube, high sensitivity oscilloscope with two independent
vertical as well as horizontal channels. It is indispensible for investigation of electronic circuits in industry, school
and laboratory. Vertical channels 10 mv rms /in. with response within -2 db from dc to 200 kc and pulse rise
time of 1.8µs... horizontal channels 1 v rms /in.within-2 db from do to 150 kc...non- frequency discriminating
controls ... internal signal amplitude calibration ... linear time base from Y2 cycle to 50 kc, triggered or repetitive,
for both horizontal channels.
S-1 2-B RAKSCOPE admirably fills the need for a small oscilloscope of wide versatility. With all the
features of the S -11 -A POCKETSCOPE, the RAKSCOPE is JANized (Gov't Model No. OS -11), and has many additional
advantages; the sweep, from 5 cycles to 50 kc, is either repetitive or triggered ... vertical and horizontal
amplifiers are 50 mv rms /inch with band -pass from 0 to 200 kc ... special phasing circuitry for frequency
comparison.
