Description
Overview
The Rohde & Schwarz NRVD is a dual-channel RF power meter that performs power, level, and voltage measurements from DC to 40 GHz. It operates as two independent measurement channels capable of simultaneous operation, with the ability to exchange data between channels. The two channels can be configured separately for completely different measurements, or the measured values can be related to each other for readout of reflection coefficient, SWR, or return loss.
Key Features
- Accurate, general-purpose, easy-to-use design
- Two independent measurement channels with simultaneous operation
- Operating modes: average power, reflection, pulse power, AM, DC
- Manual or automatic range selection
- Intelligent sensors with plug-and-play compatibility
- Remote control via IEC/IEEE (SCPI)
- Five-digit LCD display with adjustable backlighting
- Measurement results displayed with selectable resolution
- Sensor check source: highly accurate 50 MHz signal at 1 mW (0 dBm)
- Optional input/output module (NRVD-B2) with analog outputs and trigger inputs
- Frequency-proportional DC voltage input for tracking frequency-response correction
Available Sensors
The NRVD works with a comprehensive range of intelligent power sensors including diode sensors (NRV-Z1 to Z15) covering 10 MHz to 40 GHz, peak power sensors (NRV-Z31 to Z33) for pulse measurements, thermal power sensors (NRV-Z51 to Z55) for high-precision measurements, and RF insertion units (URV5 series) for voltage measurements.
Applications
- RF and microwave power measurement
- Component and device testing
- Transmission line and antenna analysis
- Transmitter power verification
- Research and development
Specifications
| Display | Measurement results are displayed with selectable resolution on a five-digit LCD with adjustable backlighting. The values measured in the two channels or one measured value plus an additional item of information are displayed. The NRVD measures pulse-modulated RF signals like the NRVS. Additionally, the modulation depth of amplitude-modulated signals can be determined from the power variation. After entering the source matching, the expected uncertainty for thermocouple power sensors can be displayed. |
| Sensor Check Source | It supplies a highly accurate, low-distortion 50 MHz signal of 1 mW (0 dBm) power for checking the sensors. |
| Input/Output Option NRVD-B2 | Each measurement channel has an analog output with selectable scaling for connection of a recorder or for control purposes. Simple automatic test routines can be implemented with the aid of the trigger input and the ready output. Another input serves for taking up the frequency-proportional DC voltage from a sweep generator for tracking frequency-response correction. |
