[Test-Equipment] El-cheapo sweep generators?

[Ian Wilson]

If the cheap eBay DDS modules are still available (they were <$4 shipped
for a while), then homebrewing something from the PIC code on the VK5TM
is an excellent way to go for an RF sweep generator. His code lets you set
start, end, steps, and marker; and one setup is saved in the EEROM. The
code is configurable for the AD8950 or AD8951, and any clock frequency.
