B&K Precision Corporation, represented in Australia by Unispan Instruments Pty Ltd , has launched the Model 4051, a programmable multifunction generator that is extremely versatile and affordable.

Model 4051 is the perfect instrument for R&D, manufacturing test systems, educational and training applications and service and repair.

The Model 4051 adds an adjustable triple output switching power supply, universal logic probe, auto-ranging frequency counter and a digital voltmeter to its standard range of functions. All of these features allow the user to analyse and measure many aspects of an electronic circuit.

Features of the Model 4051 include:

* 20MHz sweep function generator

* 35MHz universal logic probe

* 80W triple output switching power supply

* Auto-ranging frequency and totalise counter

* Auto-ranging digital voltmeter.

Using a standard 240Vac power source, the Model 4051 is capable of producing precision sine, square, triangle, +/- pulse, or +/- ramp waves over the 0.15Hz to 20MHz in 8 ranges. This encompasses sub audible, audio, ultrasonic and RF applications.

Extremely versatile, the model combines several functions such as waveform generation, pulse generation (through variable symmetry), an adjustable triple output switching power supply, universal logic probe, auto-ranging frequency counter and a digital voltmeter frequency sweep, into one device.

The instrument also provides the added convenience of a built-in frequency counter. This permits more accurate determination of output frequency than is possible with a simple calibrated dial. Course and fine tuning controls permit precision setting of the output frequency. A continuously variable dc offset allows the output to be injected directly into circuits at the correct dc bias level.

Operating as a sweep generator, the Model 4051 offers linear or log sweep with variable sweep rate and adjustable sweep time. Variable symmetry of the output waveform converts the instrument to a pulse generator capable of generating rectangular waves or pulses, ramp or saw tooth waves and slewed sine waves.

Other specifications include a TTL Output (open circuit condition for frequencies </-2MHz) of </-0.4V max. logic low level voltage, >-2.6V max. logic high level voltage with a rise time of </-15ns and 50% typical duty cycle. CMOS Output level ranges from 3.0V to 15.0V, +/-0.5 Vp-p, with a rise time of 120ns.

As a frequency counter, the unit has a range of 3.0Hz to 35MHz auto-ranging. The unit's triple output dc power supply offers output voltages of 5V/3.3V (Vcc), 0~+24V (+Vs) and 0~-24V (-Vs) with output current ranging from 0.5A to 5.0A.

Measuring a compact 13cm x 24cm x 26cm, the Model 4051 only weighs 3.4kg and is available for immediate delivery.

The instrument comes with B&K Precision Corporation's warranty, ac line cord, BNC cable with clips, logic probe and user manual. Optional equipment includes an RS-232C D-sub 9-pin Male-to-Female interface cable and Universal Solderless Breadboard Kit with banana plugs.
