The GX1200/1201 is a single-channel PXI-based Arbitrary Waveform Generator. The GX1200/1201 is a high performance waveform generator that combines many powerful functions in one small package.

PXI: A Cost Effective Format

The GX1200/1201 is a sensible alternative to GPIB-based waveform generators when developing a PXI-based test system. The GX1200/1201 provides a synergistic combination of a function generator, arbitrary waveform synthesizer, programmable sequencer, pulse generator, and modulation generator in one instrument. The GX1200/1201 delivers all this at a lower cost than comparable bench-type or VXI-based instruments. This versatility ensures that the GX1200/1201 will adapt to future testing needs as well as current ones.

High Speed Sample Rates

New technology requirements are driving communications systems to use increasingly narrow channel width. With high sample rates of 50 MS/s (GX1200) and 100 MS/s (GX1201), the GX1200/1201 is an ideal modulation source for troubleshooting new encoding schemes. The GX1200/1201 also provides high-speed waveforms to stimulate signal distortion, power line cycle dropouts, video signals, components failures and power supply transients.

2Meg Waveform Memory

The GX1200/1201 provides 2 Meg of waveform memory as standard, far more than competitive models. This waveform memory is accessible via a high-speed interface. Waveform memory is segmentable, allowing the storage of up to 4096 different waveforms rapidly and without having to download multiple times, enhancing test throughput in a way that cannot be duplicated by other competing products.

Sequences of up to 4096 Waveforms

The GX1200/1201's powerful sequencing capabilities allow linkage of up to 4096 waveform segments and/or bursts (repeated segments) into strings. A segment can be repeated up to 128K times in burst mode. Sequenced functions run continuously or are initiated by a trigger. It is also possible to mix continuous and triggered segments within one sequence. These sequencing features permit the creation of complex waveform or pulse patterns using minimal amounts of memory.

Sequences are created by writing a sequence table. Sequence table download is extremely fast because ArbConnection writes to directly to the register and does not require the overhead of an embedded controller.

Flexible triggering Capability

Combining PXI trigger lines with the GX1200/1201 sync capability transforms the GX1200/1201 into an Arbitrary Trigger Generator. In addition to continuous output, the instrument can also wait for a trigger to initiate a single waveform, a burst of waveforms or a sequence of waveforms. Triggers can also be used to advance a sequence of waveforms one segment at a time. The GX1200/1201 accepts the triggers for multiple sources: eight backplane trigger lines plus STAR trigger, front panel trigger input, and manual commands such as *TRG.

ArbConnection Software: Unlimited Source of Arbitrary Waveforms

With the GX1200/1201's ArbConnection software, you can control instruments functions, modes and features. You can create virtually unlimited varieties of test waveforms. Freehand sketch allows you to draw your own custom waveform for quick analysis of analog signals. You can use the built-in equation editor to create your own exotic functions. Add or subtract components of a Fourier series to characterize digital or analog filters or, inject random noise into a signal to test immunity to auxiliary noise.

Sample Clock Agility

The GX1200/1201 has outstanding low phase noise characteristics and carrier stability. Such characteristics are very much needed for telecommunication and channel separation applications. On the other hand, the output of the GX1200/1201 can be made extremely agile for applications needing sweep, FSK and FM. The sample clock of the instrument is derived from a DDS (Direct Digital Synthesis) circuit so controlling instantaneous frequency is a matter of changing its input bits. You, as a user, should not really care how it is done but the end result is magnificent: functions like wide-band FM, wander, linear and logarithmic sweep are easily created and executed by the generator.

A unique and extremely useful feature of ArbConnection is the FM Composer. The FM composer screen looks very much like the Wave Composer screen, except the Y-axis is provided in units of frequency, so waveforms that you create using the FM composer generate frequency change over time. You can create any arbitrary waveform shape or use the equation editor to generate exotic shapes which eventually you can use to frequency modulate your main output.

Arbitrary Waveforms

The GX1200/1201 is also extremely flexible as an Arbitrary Waveform Generator. Combined with the power of ArbConnection, there is no limit to what you can create and generate. Waveform coordinates can be imported from a variety of sources such as MathLab, ASCII files, etc. Anything you can show on one of the composer screens is downloaded in a split second and generated by the main output. Place two or more GX1200/1201's in a chassis and harness the power of multi-instrument synchronization to create multiple, phase-controlled output channels, then vary module-to-module phase offsets to create a multi-phase signal source.
