Additional Features: Intelligent measuring heads: just plug them in and measure straightaway Readout: Absolute in W, dBm, V, dBV, dBμV, relative in dB, %, A/B, B/A, A–B, B–A Remote control of all functions via IEC/IEEE bus to SCPI Two independent channels performing simultaneous measurements LC display with variable backlighting, separate digital readout for each channel, bargraph indicator Menu-guided operation with softkeys IEC/IEEE-bus interface (optionally SCPI or compatible with URV5) Entry of reference values for level and attenuation 13 digital filters for noise suppression, automatic or manual filter selection Storage of 20 complete instrument setups Input/output option with DC frequency input, analog outputs, trigger input, ready output Large variety of intelligent sensors: plug and play Rear connectors for sensors Sensor check source The NRVD covers a total bandwidth of 40 GHz and a power span from 100 pW up to the kW range.  Being individually and absolutely calibrated, the measuring heads can be interchanged as required without impairing specified error limits. The wide range of measuring heads includes thermal power sensors as well as highly sensitive diode power sensors, peak power sensors, probes and insertion units for voltage measurements.
