The Pragmatic Instruments (TEGAM) 2714A is a
20 MHz True Arbitrary Waveform Generator
for high-quality signal production.
True arbitrary waveform generation for high sample rate and extended memory applications.
The 2714A offers 12-bit vertical resolution with over 128k of horizontal memory.
It has a variable sample rate that ranges from 0.1S/s to 20MS/s.

This product is ideal for testing I and Q modulation profiles, radar or sonar simulations, complex electromagnetic simulation, ultrasound detector emulation, and a host of other applications.

Each 2714A is equipped with a synchronous trigger output.
The synchronous output allows external instruments, including two or more 2714A units, to be hardware triggered by a master 2714A unit.
This produces multiple-phase signals with highly accurate phase offsets.
Because the 2714A uses the raster scan technique and sequential addressing, there is no need to recalibrate phase offsets every time a frequency change is made.
DDS-type generators require this recalibration.

Technical data:

• 0.1S/s to 20MS/s adjustable sample rate
  
• 12-bit (0.025%) resolution
  
• Sync trigger output for multi- phase operation
  
• Waveform creation software included
  
• 10 standard waveforms
  
• 128k waveform memory
  
• Stores 100 custom waveforms
  
• 0.06% waveform distortion
  
• RS-232C and GPIB

Comes with
Control software and computer interconnecting cable.
