Thank you for the link. The data sheet raises a few questions:
The sine wave input level is specified as "1Vrms nominal 0.5V Peak to
peak." Of course, 1Vrms is ~2.8Vp-p. It is not clear what this
specification means.
Gain and noise are not specified, nor is isolation from output to
input or from the outputs to each other. These are parameters that
many buyers will want to know.
Have you characterized the NGA-DIS for phase noise? That is also a
parameter many buyers will want to know.
Does each output have its own output amplifier, or does one amplifier
drive multiple outputs through individual build-out resistors?
Does the NGA-DIS use op amps, or discrete circuitry?
What is the price?
Best regards,
Charles
