[[ | The FG501A replaced the [[FG501]] (1972) in 1981. | ||

The TRIG OUT signal is available on the front panel via a [[BSM|BSM female connector]]. | |||
===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 features 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 attenuator, not found in the non-A model. | |||
