Rohde & Schwarz NRVS 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.

Probes and Sensors - All NRV sensors and URV5 probes.

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

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

Absolute Readout - W, dBm, V, dBµV.

Relative Readout NRVS, URV55 -
dB, %W or %V relative to a stored reference value.

Analog Display - Automatic or with selectable scale.

Digital Display and Resolution - Max. 4 1/2 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 from page xxx/xxx.

Measurement Rate - See table below.

Accuracy of URV55 (without sensor) -

18 to 28°C: ±0.02 dB ± 1 digit.

10 to 40°C: ±0.04 dB ± 1 digit.

0 to 50°C: ±0.06 dB ± 1 digit.

Accuracy of Power Readout in W (NRVS/D without sensor) -
0.4% + 1 digit (18 to 28°C).
0.9% + 1 digit (10 to 40°C).
1.4% + 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), control of all instrument functions.
