The 5328A Universal Counter makes frequency, period, multiple point average, time    interval, time interval average, totalize, ratio, voltage and electronically controlled totalize measurements. Burst and CW measurements to 100MHz. Resolution of 100 ns single shot time interval measurements. Time interval averaging has a resolution better than 10 ps for repetitive time intervals as short as 100 ps. Marker outputs (operational to 100MHz) shows real time triggering for use with oscilloscope monitoring. Timebase is 10MHz with stability <3x10E-07 per month. 9-digit display with 9th digit used only with channel C functions and zero suppression to left of reading. Switchable x1 and x10 attenuators for each of the two inputs. Channel C goes up to 500MHz.

Logically laid-out front panel with simple push-button design makes the 5334B Universal    Counter one of the easiest counters to use…its capabilities make it one of the most usable    counters available. High performance starts with two matched 100MHz input channels and    displays with 9 digits per second resolution. You'll find the features and abilities of this counter are endless- with the push of a button, automatic rise/fall time, pulse width and   AC/DC voltage measurements, auto triggering and auto attenuation, as well as frequency and period measurements, time interval and time interval delay, external arming/gating for synchronizing measurements to external events, plus much more! Of course, all of this power is available via the front panel or automated using the built-in HP-IB interface. Other freat features include the ability that enables the operator to store & recall up to 10 front-panel setups.

The HP 5382A Electronic Counter covers the wide frequency range of 10Hz to 225MHz while offering sensitivity of 25 mV rms (30Hz to 10MHz) and 50 mV rms (10Hz to 225MHz). Input impedance is 1 Mohm, <40 pF and input attenuation is selectable between x1, x10, and x100.  Resolution is direct count: 1Hz in 1 sec and gate time is 0.1 sec, 1 sec and 10 sec. 8-digit LED display provides good resolution and non significant zero blanking. Rear panel input sensitivity of 250 mV rms. Timebase frequency is 10MHz.

The Fluke 1910A is a single channel Frequency Counter from 5Hz to 125MHz in a 1MOhm input impedance.  Attenuation button and Trigger Level potentiometer allows easy adjustment to the incomming signal.  Functions of Frequency, Period, Total Counter and Check Clock, in ranges of last digit of 100Hz, 10Hz, 1Hz, .1Hz and Automatic. Period reading selection for 1x10E0 up to 1x10E+3.  A reset button is used to clear the counting registered. 7 red led displays announce in good light, while other led indicators on panel shows scale and function under effect. Input ca goes up 250V RMS max.

The GoldStar function generator generates sine, triangle, square, ramp, ttl pulse, skewed sine wave under button selection, in 7 ranges from 0.02Hz to 2MHz.  Two BNC outputs for TTL output and Variable level in 50 ohms.  5 potentiometer knobs adjust Output Level (20Vpp - open, 10Vpp -into 50 ohms), Offset (DC Offset voltage from 0 to ±10V can be superimposed to output waveform), Pulse shape (Variable waveform/duty cycle symmetry) and Sweep width ( Linear sweep from 1:1 to 100:1) and Sweep Rate. This knobs works with "pull to activate", while down it assume internal set. There is a BNC front connector for VCF input, that allows the unit to receive external clock. A large multiturn (6 turns) knob is used to adjust the output frequency from 0 to 2, with large marks for 2/10 and small for 1/10 of the full scale range.  Power on and led button on front.  Unit in very good condition like new. No manual. Just power on cable. Power: 110/220Vac 50/60Hz, 20W - Size: 10Lx8Wx3H inches, 5.4lb
