Detailed Specifications
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.

Easy-To-Use Functions

Internal modulations of AM, FM, PM (PSK), FSK & PWM for waveform adjustment.
Built-in linear and logarithmic sweeps from 1ms to 500 s.
The burst mode has a selectable number of cycles per period of time.
Using remote control via USB, LAN and GPIB interface.
The programmability by SCPI commands under the remote control connection.
Precise phase adjustments and calibrations can be done from the front panel or via a PC.

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-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.

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 16-bit 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.
