The Tektronix FG501 is a function generator plug-in for the TM500 system.

The FG501 was designed by Roger Stenbock. It was replaced by the FG501A in 1981.

Key Specifications

Frequency	0.01 Hz to 1 MHz in decade steps
Output	Max. 20 V_p-p into high impedance, 10 V into 50 Ω (SN < B130000: 15/7.5 V)
Offset	Max. ±7.5 V_p-p into high impedance, 5 V into 50 Ω (SN < B130000: 5/2.5 V)
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.

-The TRIG OUT signal is available on the front panel via a [[BSM|BSM female connector]].
+The FG501 was designed by [[Roger Stenbock]].  It was replaced by the [[FG501A]] in 1981.
-The FG501 is specified at a max frequency of 1 MHz, while the "A" model is specified at 2 MHz. The FG501 features seven different functions: Sine, Triangle, Square, +Ramp, -Ramp, 50%>duty square, 50%<duty. The Duty cycle of the Ramp and pulses (not square) are determined by the equation 1/2,,f,, where the veriable ,,f,, represents frequency.
-The "A" model features only 3 functions: Sine, Triangle, Square. But the other absent functions compensated with a variable symmetry function, effectively allowing the same functionality with only three functions. The "A" model also features an attenuator, not found in the non-"A" model.
