ORTOFON The Tests, Direct Cut No 0001LP test disk.
Hitachi VC-6041B Digital Storage Oscilloscope to measure tonearm resonance frequency.

Test Results

1. Cartridge-Tonearm system resonance frequency 10 Hz. SME recommendations 8 to 13 Hz. PASSED.
2. Rumbling -50dB below 5cm/sec reference level. PASSED.
3. Frequency response 20Hz-20kHz. Meets M93E specs. PASSED.
4. Channel Separation 22dB. M93 specs 20dB. PASSED.

Trackability tests at recommended 2g VTF.

Ortofon Test LP @ 315 Hz Lateral:
40 u - low quality cheap cartridges. PASSED.
50 u - as above. PASSED.
60 u - Hi Fi cartridges. PASSED.
70 u - as above. PASSED.
80 u - Very high quality cartridges. PASSED.

HFS75 Test LP @ 300 Hz Lateral:
Test A - low quality cheap cartridges. PASSED.
Test B - Hi Fi cartridges. PASSED.
Test C - A super high-level cut. Successful performance on this band is evidence of superior tracking ability. The test should be attempted ONLY with the finest cartridges and arms and is a means of investigating tracking propensities rather than establishing tracking pressure for normal or permanent use. PASSED.

CONCLUSION The cartridge meets SHURE M93E specifications for new cartridge
