With a frequency range of 0.001Hz to 40MHz, amplitude and frequency modulation, and linear/log sweep, the FG504 Function Generator will fulfill many application requirements. But add to these features, variable rise and fall time, variable symmetry, phase lock mode, and external triggering and gating with variable phase control, and you have a function generator that can handle most every job you can imagine. Output levels up to 30 Vp-p and a 10 dB/step 50 dB attenuator help supply most every signal level you'll need. The FG504 requires 2 compartment slots in a TM 500-Series mainframe.
