FG501A
The Tektronix FG501A is a function generator plug-in for the TM500 system.
The FG501A replaced the FG501 (1972) in 1981.
Key Specifications
| Frequency | 0.002 Hz to 2 MHz in eight decade steps |
|---|---|
| Output | Max. 30 Vp-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 |
|
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, positive- and negative-going ramps, pulse ≤50% duty, and 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 three functions – sine, triangle, and square. However, it has an added variable symmetry control, effectively allowing the same functionality as the non-A model.
The FG501A also adds an output attenuator and increases the maximum open-circuit output voltage to 30 V from the FG501's 10/15 V.
