TEK URV5 Power Meter

Features

The URV 5 RF Millivoltmeter is a broadband voltage, level and power meter with high accuracy and sensitivity. It is suitable for both manual operation and use in systems. A great variety of probes, sensors and accessories allows the URV 5 to be used for all kinds of measurements.

The values measured in the two channels can be displayed separately, set off against one another or referred to any reference. For relative measurements, the difference, difference in percent, logarithmic difference or ratio is indicated (DELTAV, DELTAW, DELTA%, DELTAdB, X/REF).

The URV 5 has a fast trend indication which follows the variations of the measured value.

The URV 35 Level Meter is a precise voltage and power meter for a large variety of applications. It can be used in service and production, as well as for precision measurement in the RF and microwave lab.

The large variety of probes and sensors available opens up a wide level and frequency range. Excellent RF shielding provides precise measurements, even in the near field of antennas.

An intelligent operating concept in conjunction with an auto-range facility reduces the user's work to read the results in standard units, either as absolute or relative values. The appropriate scale is shown on the LCD display for convenient reading of the results.

Filtering, which is dependent upon the level and resolution, as well as the choice between 4 1/2- and 3 1/2-digit readout, optimizes the display of results. Each probe and sensor is calibrated individually. All relevant data of the probes are automatically evaluated in the URV 35.
