Specifications
Distortion
Fundamental frequency range: 10 Hz to 110 kHz continuous frequency
coverage in 4 decade ranges with 2-digit resolution. Destortion analyzer
and oscillator are simultaneously tuned.
Distortion measurement range: 0.01% full scale to 100% full scale
(-80 dB to 0 dB) in 9 ranges.
Detection and meter indication: true rms detection for waveforms with
crest factor £ 3. Meter reads dB and % THD (total harmonic distortion).
Meter can be changed from NORMAL to VU ballistics with switch.
Distortion Measurement Accuracy
10 Hz to 20 kHz: ± 1dB
20 kHz to 50 kHz: + 1, -2 dB
50 kHz to 110 kHz: + 1.5, -4 dB
Fundamental Rejection (3 V scale or above)
10 Hz to 20 kHz: >100 dB
20 kHz to 50 kHz: >90 dB
50 kHz to 110 kHz: >83 dB
Distortion Introduced by Instrument (input > 1V rms)
10 Hz to 10 kHz: < -95 dB (0.0018%) THD
10 kHz to 20 kHz: < -92 dB (0.0035%) THD
20 kHz to 30 kHz: < -90 dB (0.0056%) THD
30 kHz to 50 kHz: < -85 dB (0.01%) THD
50 kHz to 110 kHz: < -70 dB (0.032%) THD
Input Level for Distortion Measurement: 30 mV to 300 V rms
(100 mV range minimum).
Input Impedance: 100 kohm ± 1% shunted by < 100 pF input high to low.
Oscillator
Frequency Range: 10 Hz to 100 kHz
