Rohde and Schwarz NRVD
Dual-Channel Power Meter
Contact us for pricing and availability.
Description
The Rohde NRVD is a Dual-Channel Power Meter. The NRVD functions like two independent NRVS power meters in one enclosure performing simultaneous measurements and exchanging data with each other. The two channels can be set separately so that two completely different measurements can be carried out at the same time. The two measured values can also be related to each other for readout of reflection coefficient, SWR or return loss, for instance.
- Characteristics
- 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 wiht 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. Features
- 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
