1. Ability to adjust the output level to well below 1mV and smoothly up
to several volts.

2. Circuitry not linked to the AC safety ground to avoid hum loops.

3. Have a fixed level output to connect to the external trigger input on
a scope - so the trace remains in synch despite noise, hum and harmonics.

3. Square wave output for checking tone circuits and amplifier stability.

4. Frequency from 10Hz to 100kHz, preferably in four overlapping ranges.

5. Amplitude remains steady when frequency setting or range is changed.
6. THD not more than 0.1% with low order harmonics.

You can do all this with some very inexpensive stuff.

Bet a software ****** like YOU has never even seen the insides of one.
