The FG501A replaced the FG501 (1972) in 1981.

Key Specifications

Frequency	0.002 Hz to 2 MHz in eight decade steps
Output	Max. 30 V_p-p (into high impedance)
Attenuator	60 dB in 20 dB steps, 20 dB variable
Rise time	25 ns
Features	symmetry variable from 5 to 95%
Signals	sine, square, triangle, ramp, pulse
Features	voltage controlled frequency input (1000:1 ratio) triggering gated output with variable phase control

The TRIG OUT signal is available on the front panel via a BSM female connector.

The Phase control is effective in gated mode to control the starting phase of the generated waveform.

Differences to FG501

The FG501 non-A frequency maximum is 1 MHz, while the "A" model is specified at 2 MHz.

The FG501 features seven different functions – Sine, Triangle, Square, +Ramp, –Ramp, Pulse ≤50% duty, Pulse ≥50%. The duration of ramp and pulse waveforms is always equal to the half-cycle time of the sine, square, or triangle waveform frequency

The FG501A model provides only 3 functions – Sine, Triangle, Square – however, it has an added variable symmetry function, effectively allowing the same functionality as the non-A model

The FG501A also features an output attenuator, not found in the non-A model. Output voltage is increased to 30 V (OC) from 10/15 V.
