TEST EQUIPMENT

10 MHz General-purpose Lab Pulse Generator
The model AV-1030-C 200 ps rise time, 10 MHz user-friendly generator provides 0 to +/-5 V out (0.5, 1.5 and 5 V ranges) with pulse width variable from 5 ns to 1 ms and fall times of less than 300 ps. The output polarity is switch selectable and delay is variable up to 1 ms. Additional features include low jitter (£ 15 ps), self-explanatory controls, a manual single-pulse mode and a rugged all-metal chassis for low emissions. The instrument requires 110/220 V, 50 to 60 Hz prime power and is housed in a 4" x 16" x 12" metal chassis with SMA connectors.

Thin Sheet Tester
The model 3000T two-port coax tester measures insertion loss of thin sheets of shielding materials. The unit is quick and easy to use and does not require sample preparation. The tester can be furnished with calibration standards for m/e measurements of solid materials from approximately 1 MHz to 1 GHz.

Radar Return Simulator Integrated Assembly
The model 1663 radar return simulator assembly operates in Ku-band and is designed to provide a programmable phase and amplitude relationship between two channels to simulate radar return signals. The module interfaces with a waveguide manifold, which, in turn, interfaces with waveguide ports of the radar system. The unit contains two in-phase/quadrature (I/Q) vector modulators, five PIN diode switches, one PIN diode transfer switch, one high speed pulse modulator, two isolators, two couplers and one bandpass filter. The unit features better than 1° phase accuracy between channels, built-in test circuitry and an internal EPROM correction table that is used to calibrate out system errors. Size: 5.3" x 3.5" x 0.7".

RF/IF Coaxial Switch Matrix
The model 10840 RF/IF coaxial matrix is a switching unit that connects any 32 inputs to any combination of 32 outputs under RS-232 or IEEE-488 control. The unit's bandwidth of 5 to 250 MHz covers high frequency and VHF bands as well as the 70 to 160 MHz IF range. The system features unity gain at full fanout, which results in a high degree of versatility. Speed setup time up to 40 stored switching configurations may be recalled.

Wideband Noise Generator
The model TAS 420 wideband noise generator generates precise, user-programmed levels of additive white Gaussian noise, which is a critical function for the development, characterization and test of modern communications equipment. The unit meets the emerging test requirements for cable models and other community antenna television-based communications equipment. Additonal features include easy-to-use front-panel controls, flash-based calibration constants, repeatable test conditions, a burst noise model and dynamic level variation capability, and an IEEE 488.2 control interface. Price: $12,950.
