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

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