Audio connections
1. Audio input cable from Low Distortion Oscillator output to right
channel input
2. 1/4" shorting plug to left channel input
3. Audio output cable from right channel output to Level Meter input
4. Audio terminator (100k) plug to left channel output
Procedure
1. Apply a 1 kHz signal at -25dBV (159mVp/p) to right channel input. Set
Level Meter to measure right channel output as the OdB reference. Make
sure meter has 30 kHz or audio bandpass filter ON.
2. Unplug input to right channel. This will short out both right and left
channel inputs.
3. Measure level on right channel output. Acceptable reading will be < -75
dB (referenced to 1 kHz output level; typical reading will be about -85dB.)
4. Swap right and left channel audio connections and repeat steps 1-3 on
left channel.
