Palo Alto, Calif.Continuing its thrust to be at the forefront of LXI (LAN eXtensions for Instrumentation) test gear, Agilent Technologies Inc. introduces what it says is the industry's first LXI-certified 20-MHz function/arbitrary waveform generator with variable-edge pulses and pulse-width modulation. It's priced at about $1850.
Part of the company's Agilent Open program, the updated Model 33220A Function/Arbitrary Waveform Generator joins a list of no less than 47 LXI-certified products from Agilent.
Agilent Open is a combination of test system hardware, I/O, and software tools. Its purpose is to help create streamlined test systems that are easy to enhance and maintain.
The 33220A waveform generator uses DDS (direct digital synthesis) to create a stable and accurate output signal. The DDS used in the 33220A operates to deliver a clean low-distortion signal.
In use, the DDS lets the 33220A generate signals from the micro-Hertz regime out to 20-MHz, feeding 50-ohm unbalanced loads.
The box also gives you square waves with fast rise and fall times up to 20-MHz, as well as linear ramp waves up to 200-kHz. The 33220A can also generate variable-edge-time pulses up to 5-MHz. With variable period, pulse width, and amplitude, the 33220A is suited to a variety of applications requiring a flexible pulse signal.
You can also use a 33220A to generate complex custom waveforms. With 14-bit resolution, and a sampling rate of 50-Msamples/s, the 33220A also lets you store up to four waveforms in non-volatile memory.
In addition, Agilent IntuiLink Arbitrary Waveform software lets you create, edit, and download complex waveforms using a waveform editor. Alternatively, you can capture a waveform using Agilent's IntuiLink for Oscilloscope, and then send it to the 33220A to be output.
All of the 33220A's major functions are accessible with a single key or two. The unit's knob or numeric keypad can be used to adjust frequency, amplitude, offset, and other parameters. You can also enter voltage values directly in Vpp, Vrms, dBm, or as high and low levels. A Graph mode is also available for visual verification of signal settings.
Timing parameters can be entered as frequency in Hz or in seconds. Internal AM, FM, PM (phase modulation), FSK (frequency-shift keyed), and PWM (pulse-width modulation) modulation also let you modulate waveforms without the need for a separate modulation source.
Linear and logarithmic sweeps are also built in, with sweep rates selectable from 1-ms to 500-seconds. A Burst mode also lets you choose a selectable number of cycles/period of time.
For connectivity, IEEE-488/GPIB (General Purpose Interface Bus), LAN, and USB (Universal serial Bus) interfaces are included. The 33220A Function/Arbitrary Waveform Generator can also be programmed using SCPI (Standard Commands For Programmable Instruments) commands.
Optionally, you can also fit a 33220A with an external frequency reference. The reference lets you sync to an external 10-MHz clock, or to another 33220A, or to Agilent's 80-MHz Model 33250A function generator. Phase adjustments can be made from the front panel, or via a computer interface.
