Model 1940A 400 MHz, four-channel direct digital synthesizer in a 1U rack-mountable case features four independent 1940A frequency low-noise sine-wave outputs that can be individually set to any value between 200 kHz and 400 MHz with a resolution of 1 Hz. Each output frequency is provided on two buffered output connectors for a total of eight outputs. Amplitude is +4 dBm and each output channel can be programmed with 10, 20, 30, 40, 50, or 60 dB of attenuation. De-vice contains an internal temperature compensated crystal timebase that is stable to. Menu-based software is included.
