Wavetek model 185 5 Mhz lin/log sweep generator, can generate and sweep sine, square, triangle, positive pulse, and negative pulse waveforms from .0001 Hz to 5 Mhz. Sweep can be linear, lograthmithic, or stepped at 100 microseconds to 100 seconds rate, can operate in continuous, triggered, gated, or sweep mode. Amplitude can be varied by a 0 to -80 db step attentuator and a continuous 0 to -20 db vernier, max output approx. 20V p-p open circuit, 10V p-p into a 50 ohm load. Waveform symmetry can be continuously varied from 1:19 to 19:1; DC offset adjustable +/- 10V open circuit, +/- 5V into 50 ohm load. Frequency can be controlled by standard VCG control voltage input, has TTL compatible pulse output. Front panel jacks for VCG IN, GCV OUT, SWP OUT, TRIG IN, PULSE OUT (TTL), and 50 ohm output. Rack mount panel with three BNC feedthrough jacks mounted on each side for auxiliary connections, in excellent condition. Power requirement 90V – 250V 50 Hz – 400 Hz AC. A very versatile piece of test equipment. Used checked for function, not calibrated.

Wavetek model 131 VCG Generator is a precision source of sine, square, and triangle waveforms over a frequency range of 0.2 Hz to 2 MHz. Output variable over a 40 db range, max output 20V p-p open circuit, 10V p-p into a 50 ohm load. Front panel has jacks for 50 ohm output, and VCG input which allows either DC control of frequency or AC input for FM modulation of signal over a 1000:1 range. Back panel has a sync output jack, greater than 1V p-p square wave into open circuit at selected frequency; also DC offset control. Used checked, not calibrated

EG&G Princeton Applied Research 162 Boxcar Averager with 166 Gated Integrator

ECG JA-30 Soldering Stand and Tip Cleaners, ECG JA-30 soldering stand and tip cleaners have an integral holder for your pencil iron. The tip cleaner is a coiled wire type that doesn’t burn and won’t allow solder to stick. A quick wipe of your iron through steel-wool style cleaning ball is all it takes to provide you with a clean tip to accept smooth solder flow. And, when you need both hands free you’ll have a convenient place to put your pencil… right in the soldering iron stand. New,
