Detailed Specifications – Picotest G5100A Arbitrary Waveform Generator
The new Picotest G5100A Waveform Generator uses direct digital synthesis (DDS) techniques to
create a stable, accurate output signal for clean, low distortion sine waves. The G5100A offers
10 standard waveforms and user defined arbitrary waveforms with 14 bits resolution. It also
provides you 16 bits pattern out and a synchronized clock. Moreover, the external frequency
reference lets you synchronize to an external 10 MHz clock. The G5100A has intuitive panel
operation; the menu is structured and convenient. All shortcut keys are fast and easy to access.
The G5100A provides you the flexibility to create the waveforms you need. Also you can store
up to 4 waveforms (4 x 256K points) in nonvolatile memory.

User Friendly Operation
The front-panel operation of G5100A is simple and user friendly. Users can enter all functions
with a single key or two, and use knob or numeric keypad to adjust frequency, amplitude, offset
and other parameters. Otherwise, users can also directly input voltage values in Vpp, Vrms,
dBm or high & low levels. Timing parameters can be entered in Hertz (Hz) or second.
Users can easily use the following functions.
Functions and Waveforms
The Picotest G5100A 50 MHz Function / Arbitrary Waveform Generator can create stable,
precise, clean and low distortion sine waves by using DDS (Direct Digital Synthesis) Technology.
With fast rise and fall times up to 25 MHz for square waves and 200 KHz for linear ramp waves,
the G5100A also can reach users demand on waveforms. It can also generate variable-edgetime pulses up to 10 MHz. With variable period, pulse width and amplitude the G5100A is
perfectly suited to applications requiring a flexible pulse signal.
Pulse Generation
If a unique Waveform is needed, the G5100-A can generate variable-edge-time pulses up to 10
MHz. With variable period, pulse width and amplitude the G5100A is perfectly suited to
applications requiring a flexible pulse signal.
Custom Waveform Generation
The G5100A can generate complex custom waveforms. With 14-bit resolution and a 125 MSa/s
sampling rate, the G5100A gives users the flexibility to create waveforms. It also allows users to
store up to 5 waveforms, 4 (4 x 256k Points) in nonvolatile memory and 1 in volatile memory.
The G5100A’s Waveform Editor Software allows users to create, edit and download complex
waveform. In addition, by using the software, users can retrieve waveforms from Agilent MSO
8104 oscilloscope.
Support External Freq. Synchronization
The G5100A’s external frequency reference allows users to synchronize an external 10MHz
clock to another G5100A, or to any other unit which can support 10MHz frequency-input
function.
Data Transmission via Pattern Out
The WavePatt software adheres to the waveform editor. It allows users to create and store 16bit data in the G5100A’s nonvolatile or volatile memory. Then, according to application
purposes, users can transmit data via Pattern Out, located in the rear panel.
