Simpson Handiscope
#1

O-scope questions:

I just picked up a Simpson Handicsope because I liked the vintage look Icon_smile and I want to learn how to use an O-scope.

It needs a restoration like any 50's vintage device. One tube tests bad and all the caps are original. A manual was hard to find but one is on the way and I hope it includes a schematic.

It has no probe and I am wondering what to get. Online info says the input resistance is .1meg@ attn. x1 and .5 Meg @attn x100. Capacitance 40 uuf @ attn x1 35 uuf @ attn x100.
It has banana plug inputs.

Any clues on where to start looking for probes?

The old sales info on this scope says:

Frequency Response of Vertical Amplifier: From 15 cycles/see
to 100 Kc/sec, flat within ±1 db; 6 db down at 250 Kc/sec; usable
to 1 Me/sec.

Maximum Vertical Deflection Sensitivity: 30 Millivolts RMS/
inch.

Frequency Response of Horizontal Amplifier: From 15 cycles/
see to 20 Kc, flat within ±1 db; 6 db down at 100 Kc/sec.

Maximum Horizontal Deflection Sensitivity: 0.7 volt RMS/inch.
Z-Axis Sensitivity (Voltage Required to Extinguish Beam):
20 volts RMS.

Calibrating Voltage (at 117.5 VAC power source): 1 volt pop
±10%.

Maximum Input Voltage: 400 volts peak.

Input Resistance: 0.1 Meg (at atten. x 1); 0.5 Meg (at atten. x 100).

Input Capacitance: 40 uuf (at atten. x 1); 35 uuf (at atten. x 100).

Sawtooth Sweep Range: 15 cycles/see to 80 Kc/sec.

Power Consumption (at 117.5 volts AC): 50 watts ±10%.
