A MultEWaveform Generator. The A is a Function/Waveform Generator with the precision and versatility to produce numerous waveforms. Its feature. This manual may contain references to HP or Hewlett-Packard. product name/ number was HP XXXX the current name/number is now Agilent XXXX. For. HP As are complex, but more likely to be repairable. The HP A was already the one I was preferring because I like the adjustment.

Its feature set includes accurate sine, square, and triangle waves, with ramps and pulses available using variable symmetry.
For increased versatility, the Arbitrary waveform mode allows a countless number of user defined waveforms. Since complete programmability is provided, all of these capabilities are available for ATE systems, as well as bench applications. The A provides sine, square and triangle waveforms from 0. Continuous waveforms are provided with high accuracy and low distortion, with frequency accuracy on the upper ranges of 0.
A post-attenuator summing technique is used providing large ac signals with small offsets and vice versa. The A’s N Cycle burst mode generates an integer number of complete cycles at each trigger.
Bursts of 1 to cycles are possible for use in applications ranging from sonar testing to digital circuits. Like burst mode, gate mode can be triggered internally or externally.

In gate, the A output consists of complete cycles, pulses or Arbs which start when the trigger is true, and stop after the trigger goes false. In gate and burst modes, the full frequency range applies for sine, square, triangle, pulse, and ramp waveforms. The Fin X Fin modes provide powerful phase locking capability. Since the A phase locks to the plus or minus edge of the trigger signal, it can lock to a variety of signals such as sines, squares, pulses, ramps, and others – with complete control of output function, symmetry, N, phase, amplitude and offset.
Multi-frequency measurements can be made with the A’s sweep capabilities. Linear, logarithmic, and manual sweep make measurements of filters, amplifiers, and other networks convenient and accurate. X drive, marker, and trigger output signals are also provided.

For specialized low frequency applications, the A’s Arbitrary ARB waveform mode lets you create custom waveforms as a series of voltage ramps or vectors. Values are easy to enter from the front panel using the modify knob as a “pencil” and an oscilloscope as a “pad”. For remote programming, use a desktop or mainframe computer to calculate the values, then program them using the HP-IB.
Arb waveforms are automatically stored in non-volatile memory for quick recall. A square wave trigger source is included for generation of complex waveforms with a single A. This signal is provided as an output for synchronizing the A to other devices.
Because all jp panel controls are programmable, the A’s precision and versatility can be utilized in automatic test systems.
System efficiency can be improved with standard features such as Service Request SRQ interrupt capability and buffered transfer mode.
In yp test environments, the A’s Query commands can be used when an operator and computer are sharing control of the instrumentation. Parameters can be read from the A into the computer where its computational capabilities can be utilized.
With complete control of each vector, the modify knob is used as a “pencil” to draw the waveform on an oscilloscope. After unit vectors have been inserted, use modify to set the marker, VMKR, to 1. Then set the height of 1 to Amplitude and frequency can now be set without affecting the vector values.
Providing the finest test equipment solutions since 1992
Waveform parameters are automatically stored in non-volatile memory while they are being created. Later, if a slightly different waveform is needed, just use the marker to select an individual vector, and modify its height and length without affecting the height and length of the other vectors.
