Expands the measurement range of the NF-5030 to 240V. A "must have" for any conductive measurement (DSL, power line, circuits etc.).


Our special Active Differential Probe ADP1 for the SPECTRAN NF-5030 Spectrum Analyzer 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).

Its 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 an mains adapter (included).


Every probe goes through rigorous testing in our laboratories before dispatched.


Made in Germany:

All Aaronia probes are developed, individually produced and calibrated in Germany at the Aaronia factory. This guarantees highest standard so that Aaronia can offer every customer a full 10 years warranty for the ADP 1.
