HP Model 339A Distortion Analyzer
- Ultra low distortion measurements
- Built-in low distortion oscillator
- Automatic
- True RMS detection
Distortion Measurement Set
Ultralow distortion measuring system complete with total harmonic distortion (THD) analyzer, true rms voltmeter, and sinew***e oscillator. THD measurements over the 10 Hz to 110 kHz frequency band, including harmonics to 330 kHz. Also features built-in tracking oscillator.
Distortion Measurements
- fundamental frequency range is 10 Hz to 110 kHz with 2 digit resolution
- measurement range is 100% to 0.01%, (0 dB to -80 dB)
Oscillator
Frequency range is 10 Hz to 100 kHz with 2 digit resolution. Output level is variable from 4 V rms to 1 mV rms.
Oscillator distortion ( >600 ohm load, <3 Vrms)
| 10 Hz to 20 kHz | < -93 dB (0.0022%) THD |
| 20 kHz to 30 kHz | < -85 dB (0.0056%) THD |
| 30 kHz to 50 kHz | < -80 dB (0.01%) THD |
| 50 kHz to 80 kHz | < -70 dB (0.032%) THD |
| 80 kHz to 110 kHz | < -65 dB (0.056%) THD |
