Option 730- Active Differential Probe

Our special Active Differential Probe ADP1 offers a potential free measurement and also expands the measurement range up to 240V. With this probe the signal will not be influenced (potential free measurement). It also protects the SPECTRAN Spectrum Analyzer input against high voltages up to 1400V (CAT3). It’s a “must have” for direct cable-measurements on DSL, ADSL, VDSL, free running oszillators, mains etc. Included in delivery is a special grounding kit which protects the unit against static electricity (ESD). This is very important at long time measurements. Power supply is possible with the internal cells (4 x AA, not included) or, at long time measurements, with a mains adapter (included).
