Test Equipment

Here is some of the test equipment I use.

• Manual Spectrum Analyzer
• Elsie L/C meter
• Elsie homepage
• Clamp on RF current probe 1
• Clamp on RF current probe 2 (split toroid)
• Noise Bridge
• Noise Bridge schematic 1
• ARRL Noise Bridge schematic
• Octapus curve tracer
• Octapus curve tracer info
• Signal Injector/Audio tracer
• Signal Injector/Audio tracer info
This was built into an old RadioShack Signal Injector case I had laying around
• N5ESE RF Probe
• N5ESE RF Probe info
• Chart: RMS Volts to DBM to Watts (use with RF probe)
• Calibration chart for my germanium diode RF probe
• Spice model of 1N34A based RF probe
• Soundcard Oscilloscope
• Probe for Soundcard Oscilloscope
• Spectran (Audio Spectrum Analyzer)
• Spectrum Lab (Audio Spectrum Analyzer)
I have used these in combination with my noise bridge to characterize crystal filters in the ATS3.
• FT817 (siggen/counter/wavemeter/etc)
I find the FT817 to be a great piece of test gear.
I have used it in combination with Ham Radio Deluxe as a spectrum analyzer
to check the harmonic output of some qrp rigs.
