The Fluke / Wavetek 100 MS/s Synthesized Universal Waveform Generator is a really great product.  It has it all;  outstanding capabilities, specifications and most important "ease of use."  The unit is in excellent physical and electrical condition and includes a comprehensive manual.


Fluke's 395 Universal Waveform Generator provides the functionality of seven instruments for the price of one. You can use it as an arb, pulse generator, function generator, noise generator, sweep generator, trigger generator, or modulation source. Whatever the mix of your applications, the 395 is the best price/performance choice.

The latest digital technology, coupled with Fluke's innovative design, means that the 395 can provide the functionality of seven instruments for the price of one. The 100 MS/s 395 has the power and flexibility to provide the right signals for applications ranging from in-circuit testing of semiconductors to the complex pulse patterns required in communication testing. And no other waveform generator provides such an easy and low-cost solution to performance characterization testing of all kinds of electronic devices.

Arbitrary waveform generator

The 395 takes its place in the impressive Fluke family of synthesized arbitrary waveform generators as the worldwide price/performance leader among single-channel arbs. There simply isn't another 100 MS/s arb on the market that can match its price, especially when you consider the supporting features. User-defined (arbitrary) waveforms can be generated at clock rates from 100 mS/s to 100 MS/s with 12 bits of vertical resolution and 64k (256k optional) points of horizontal memory. Direct Digital Synthesis (DDS) techniques are used to provide accuracies comparable to those available in expensive frequency synthesizers.

A waveform sequencing feature allows up to four waveforms to be linked in a sequence for creating long waveforms.

Arbitrary waveforms can be created from the front panel or remotely downloaded via the RS-232 interface (an RS-232 cable is included with the 395) or optional GPIB interface. The GPIB option includes direct DSO waveform transfer, which allows you to upload waveforms directly into the 395 that have been captured with any of 25 different digital storage oscilloscopes from a variety of vendors. Fluke also offers Wave Form DSP2, a software tool that makes waveform creation, modification, and downloading easy over either interface.

These are the kinds of high-performance specifications that make the 395 the arb of choice for a variety of applications that require complex, nonstandard waveforms from simulating power line disturbances such as drop out and spiked signals to providing complex signals for pressure sensors used in mechanical testing.

Function generator

With the introduction of the versatile and low-cost 395, there's no longer any reason to buy an ordinary function-only generator. The 395 generates 16 standard waveforms: square, sine, positive and negative ramps, pulse, pulse train, five different noise functions, triangle, positive and negative haversines, (sin x)/x, and dc. And the performance specifications are first rate, providing square waves to 50 MHz, sine waves to 40 MHz, and triangles to 10 MHz, with synthesized accuracy and outputs up to 10 Vp-p into 50W. Direct digital synthesis enables 10-digit frequency resolution for sine waves to 20 MHz and for most other standard waveforms to 100 kHz. Waveforms can be output continuously or in triggered, gated, or swept modes for applications like simulating input signals to sensors. Other capabilities give you the flexibility of the very best function generators including frequency and amplitude modulation, and summing the 395's waveform with an external signal.

Noise generator

The built-in noise generator is ideal for applications where precise noise is required, such as testing electronic engine module noise susceptibility in automobiles. Extensive noise generation capabilities are provided by 5 programmable noise functions: analog (white) noise, digital noise, comb function, signal-plus-noise, and signal-plus-comb. Other programmable features include sequence length for white and digital noise, bandwidths to 10 MHz for comb and white noise, bandwidths to 50 MHz for digital noise, and noise-to-signal ratios from 1% to 99%.

Pulse generator

The 395 has a built-in pulse generator that offers a greater degree of control over pulse shape and amplitude than many other pulse generators. Simple pulses up to 10 MHz can be generated. You can create complex pulse trains of up to 10 pulses with individually programmable rise time, fall time, width, level, and negative or positive delay (with respect to the sync pulse). This versatility makes the 395 suitable in pulse applications as diverse as measuring the baseband frequency response in a microwave system, measuring the real-time impedance of biological cells, and testing propagation delay in electronic circuits.

Trigger generator

The 395 makes a great trigger generator for devices under test, whether you are using standard functions or user-defined waveforms.

Burst count is programmable from 1 to 1,048,575 cycles. Gated mode provides continuous output of the waveform for the duration of the gating signal. Four different trigger sources are available for maximum versatility: internal trigger generator with programmable trigger period, external signal with programmable trigger level and slope, remote trigger command, and manual trigger key.


Sweep generator

Use the 395 as a sweep generator for performance characterization and frequency response testing, such as testing amplifier response or rapid cycling of a mechanical servo. Standard or arbitrary waveforms can be swept in one continuous range from 1 mHz to 20 MHz. Triggered and manual sweep operations also can be performed. Seven sweep modes, with linear and logarithmic sweep spacing, a TTL level sweep marker, and a ramp output give you the flexibility you need. There's even a pen lift function for use with chart recorders.

Modulation source

If you do communication or audio design and test, the 395 offers internally generated amplitude modulation and frequency modulation, as well as externally controlled amplitude modulation in two modes.

Convenience and Versatility

Fluke designed the 395 for user convenience. The user screens are tailored to the particular jobs you want to perform, such as setting up a pulse generator or a noise function.

From any screen, you can access help screens that guide you in using the instrument's extensive capabilities. And you can store at least 10 instrument set-ups so you don't have to spend valuable time duplicating past effort.

Low cost of ownership is assured by the high reliability and ease of calibration of the 395. Calibration is performed with covers on in less than 15 minutes, under front panel or remote control.
