HAMEG HZ100 Differential probes
- Hameg HZ109, This is a Hameg HZ109 Differential probe 1:1 (30 M Hz), 10:1 (40 M Hz) In the case of measurements on power supplies, thyristors & power MOS-Fets, the high input resistance of >2MO of the differential probe is very advantageous, as it causes a very high resistance separation from the probe output. In combination with a Safety Class I oscilloscope which is galvanically connected to protective earth (PE), the resistance between the differential inputs exceeds 2MO with respect to earth. This prevents galvanic hum, which appears if both the unit under test & the measuring input have different earth connections. Hameg HZ109 Differential probe 1:1 (30 M Hz), 10:1 (40 M Hz)
