The Telepost LP-500 should be ready for orders at Dayton. Price is
reported to be between USD $700-$800. It's a combination directional
wattmeter and basic oscilloscope with limited spectrum analysis. The device
can sample two RF couplers and perform amplifier linearity testing, show
occupied spectrum and transmitted waveform. I believe the final version
has a provision for an external trigger to accurately capture CW timing
The LP-500 lacks the complex Z measurement ability of the LP-100A model, but
I rarely use that function on the desk. I find that VNA devices with USB
connectivity are more convenient to use in and away from the station
desktop.
