Up
The 148A AM/FM/PM Generator gives you a one instrument source of modulated waveforms. It has two generators: a main function generator, with full function generator versatility, and a modulation generator, a convenient source for modulating and triggering waveforms or a second, independent signal source. 0.002 Hz to 20 MHz at up to 30 V p-p. Accuracy is ±(1% of the setting + 1% of full range) on the center settings and ±(2% of the setting + 2% of full range) for x.01-10 and x10 M.
Testing: This unit has been tested, with my Tektronix 475 oscilloscope. As you can see, it produces various waveforms quite nicely, with what appears to be correct voltages.This unit cost the feds $1,870, you can own it, still in excellent condition, at a fraction of the cost. The army got rid of it because they bought new toys. You can now play with their old stuff. :NIIN: It sells for $995.00 at Tucker Electronics.
This unit takes a standard computer cable and ships without one.
