So the question is whether you can make a good PC card digital
oscilloscope for $100.00. You need an oscillator, frequency divider,
PLL, sample & hold, and DAC as well as the PCIe interface. I seriously
doubt that this is possible for $100.00 but it does depend on the
maximum input frequency you wish to use, sample rate, and the accuracy
(and number of bits) needed. Actually, you can spend over $100. on a
good DAC
You can get a 2.4 GHz spectrum analyzer for $129.

If a 2.4 GHz spectrum analyzer can be sold for $129, why not a lower
frequency unit?
This device isn't really a digital spectrum analyzer. It is a sweeping
RF signal strength meter. Such a device is quite useful but it isn't
going to work for lower frequencies.
