HP 4194a Impedance / Gain-Phase Analyzer Opt 375 (75 ohm) The 4194a has a wide frequency range of 100 Hz to 40 MHz for impedance measurements. For Gain-Phase measurements the frequency range is 10 Hz to 100 MHz 7-1/2\" color display with Rectangular or Table display format Option 375 : 75 ohm system Impedance Measurements: Frequency : 100 Hz to 40 Mhz |Z|, R, X : from 100 microohm to 1.6 Megohm |Y|, G, B : from 1 nS to 10 S Phase : +/- 180 degrees with 0.01 degree resolution L : 100 pH to 1 KH C : 0.1 fF to 10 mF D: 0.0001 to 10 Q : 0.1 to 1000 Oscillator level: 10 mV to 1 Vrms DC Bias : -40 V to 40 V, with 10 mV resolution Swept measurements by Frequency, OSC level, or DC Bias Gain-Phase Measurements: Frequency : 10 Hz to 100 Mhz Tch / Rch: +/-120dB, 0.001dB resolution Tch , Rch: -107 dBm --5 dBm (0 dB Attenuator) : -87 dBm - +15 dBm (20 dB Attenuator) Shown measuring a 100 ohm standard resistor in Impedance Mode (resistor not included) Shown measuring a 10 pF capacitor standard in Impedance Mode (capacitor not included) Shown measuring a 21.4 MHz band pass filter in Gain-Phase Mode (filter and cables not included) I have checked this unit with various resistors, capacitors, and inductors at several frequencies and have gotten accurate results. I have tested the Source at several frequencies and amplitudes, and they were correct I have checked the DC Bias at several voltages and they were correct. I have sent the instrument several commands by the HPIB, and it responded correctly. I have stored and retrieved tables and settings in the instrument\'s memory and it operated properly. No other tests have been performed on the instrument Serial Number 2830 J 03206 All photos are of actual unit The Camera Flash makes the screen look a little washed out in the pictures, but it is nice and bright in real life This unit is good cosmetically, with some small scratches on the front and some scrapes and dings on the case. Comes with CD with copy of operation & service manuals (PDF), power cord, interconnect cables between the Control unit and the measurement unit Payment by Paypal, Check, or Bank Transfer (checks must clear before shipment) I can ship on your UPS, FedEx, or DHL if you have an account that can be charged for shipping costs.
