The Model 92 Series RF Mi!IIvoltmeter provides an accurate readout of measurements from the low radio frequencies to the gigahertz region, over a voltage range of 200 jjV to 3 volts. It is a programmable, solid-state instrument of high sensitivity and accuracy, characterized by high input impedance (see Figs. 1 and 2), excellent stability, and low noise. The Model 92 exhibits true rms response for input signals up to 30 millivolts, gradually approaching peak-to-peak above this level „ The meter, however, is calibrated in rms above this region. Input and output connections for externa! control and readout are provided by a 22-pin card-edge connector at the rear of the instrument. A linear dc output, whose level is proportional to the rf input voltage, is also provided at a rear connector,, This may be used to drive a recorder, remote indicator, or Other analog devices. The 92 offers a convenient and accurate means for making a wide variety of measurements. Typical uses of this instrument include: In transistor testing the instrument may be used to measure p, fj-, and Other transistor parameters. VSWR and return loss measurement using the Model 92 Series with bridge methods, directional couplers, and adjustable or slotted lines. Gain and loss measurements in wide-band amplifiers, including such design characteristics as stage gain, flatness of the pass band, upper cut-off or corner frequency, negative feedback factors, and Other parameters. Proper adjustment of tuned circuits in narrow-band amplifiers. The adjustment, measurement of performance, and evaluation of rf filter parameters. Measurement of vswr or return loss and attenuation of rf attenuators. Measurement of output levels of signal generators, adjustment of baiuns, harmonic distortion of rf signals, and adjustment of circuits for minimum voltage (null) or maximum voltage (peak). The Model 92 is available in several optional configurations with a basic accuracy of 1% rdg. + 1% fs„ The standard features of the Instrument are: Remote programmability Measures from 200 jjV to 3V* from 10 kHz to 1 .2 GHz. True rms response to 30 mV** Convenient push-button ranging. DC analog output. High input resistance, low input capacitance. Overload protection to 400 Vdc to 10 Vac. VSWR less than I e15 up to 1.2 GHz* * To 300V, up to 700 MHz, with accessory 100:1 divider. ** To 3V, up to 700 MHz, with accessory 100:1 divider. The characteristics of the instrument include: high reliability, fast warm-up (1 minute), long intervals between calibrations, Plug-In PC boards for ease in servicing or modifying, light weight, and Other advantages of solid-stage design.
