Home Products ASX-16C/D

Multiple Frequency Signal Generator

The ASX-16C/D is a remote-controlled signal generator with
remote frequency trim and base levelling. It has outstanding
noise and distortion characteristics and offers the ability to
obtain full band frequency randomization. Available 240 composite
channel loading with 100 dB down distortion.

The Model ASX-16C/D is the latest version of the ASX-16 model line which was first introduced in the early 1980's. The 'Blue Box" might look the same on the outside, however the modules inside are what set it apart from it's predecessors and competitors. New advancements offer improved amplitude linearity, output power, randomized frequency trim, phase noise and hum. Frequency pullability and multiple station correlation are also now possible with the ASX-16C/D.

The Model ASX-16C/D also provides linear monotonic carrier level control over a 15 dB range in 0.025 dB steps. All operations are controlled remotely, using the GPIB (IEEE-488) interface. An internal frequency counter option is available which allows for rapid checking and setting of the carrier frequencies.

Options Include: NTSC, PAL I, PAL B/G, Cenelec in a single unit.
