Rohde & Schwarz NRVD Dual-channel Power Meter

Characteristics

Measurement Functions - Average power, pulse power, peak envelope power. AM, reflection, DC voltage (depending on sensor).

Frequency and Level Range - DC to 40 GHz, 100 pW to 30 W, 9 kHz to 3 GHz, 200µV to 1000V (depending on sensor).

Probes and Sensors - All NRV sensors and URV5 probes.

Display - LCD for digits, units, menu-guided operation and analog display, adjustable backlighting.

Display of Results - Single-channel (with optional display of correction frequency) or dual-channel.

Absolute Readout - W, dBm, V, dBµV, dBV.

Relative Readout - dB, difference, percent and ratio, relative to a stored reference value or to the second measurement channel; VSWR, reflection coefficient, return loss in dB, AM modulation depth.

Analog Display - Automatic or with selectable scale.

Digital Display and Resolution - Max. 4.5 digits, resolution selectable (0.1/0.01/0.001 dB).

Display Filtering - Averaging over 1 to 512 readings to reduce display noise; manual or automatic setting depending on measurement range and resolution.

Display Noise - See sensors.

Measurement Rate - See table.

Accuracy of Power Readout in W (without sensors) -
0.4% (0.3%) + 1 digit (18 to 28°C)
0.9% (0.8%) + 1 digit (10 to 40°C)
1.4% (1.3%) + 1 digit (0 to 50°C).

Zero Adjustment - Manual or via IEC/IEEE bus, duration approx. 4 s.

Frequency Response Correction - Sensor-specific calibration data taken into account; numerical entry of test frequency (keyboard or via IEC/IEEE bus) or by frequency-proportional DC voltage.

Attenuation Compensation - External attenuation or gain taken into account; data entry via keyboard or IEC/IEEE bus, range ±200 dB.

Entry of Reference Value - Measured value on keystroke or numerical entry via keypad or IEC/IEEE bus.

Reference Impedance - For conversion between voltage and power, automatic readout of reference impedance from sensor data memory or numerical entry via keyboard or IEC/IEEE bus (for RF probe).

Remote Control - IEC 625 (IEEE 488), SCPI, control of all instrument functions.
