Low-cost generators are implemented with analog circuits that feature continuously variable frequency and output voltage.

The BTC broadcast test center from Rohde & Schwarz furnishes a testing environment for nearly all audio, video, and multimedia applications, enabling users to perform end-to-end tests in real time ...

This audio frequency generator is a triggered signal generator. When a positive pulse of about 6 volts (minimum) is fed to the circuits input , a modulated audio signal comes out of the output.

Designed for audio product testing, the VP-8192A, -8193A and -8194A AM/FM signal generators feature a bandwidth from 100 kHz to 140 MHz and a 0.1 dB electronic attenuator with ...

The AG52 analog signal generator offers fast rise time square waves, lower noise floor and more for APx audio analyzers.

I realise diamond buffers have their limitations, but at least they are fast (in modest rf terms) and have good driving capability. All the transistors are on all the time, so there are no delays ...
