Description:
The new family of MICRORAD Radar isotropic probes, Model ER, represents a major breakthrough in the area of isotropic measurement of impulse signals.

In conjunction with the NHT 3DL / NHT 3D meter it is the first system on the market which allows the operator to measure the emission levels from Radar sources and to demodulate the signal.

The introduction of the envelope sampling technique allows the operator to:

– immediately visualize the pulsed signal in the time domain on the NHT 3DL graphical display and read the Tau, PRF and Duty Cycle values at the same time

– immediately read the peak and average value on the display of the NHT 3D meter while providing a graphic analysis of the pulsed signal in the time domain on PC display.

This innovative technique opens new perspectives of analysis, allowing the operator to distinguish and evaluate multiple intermittent or pulsed signals commonly utilized within the
Telecommunications and Radar sectors.

These features offer the following advantages:

• Reliable identification of the source
• Exact calculation of the energy value of the source according to CEI 211-7/B Possibility to measure multiple pulsed sources simultaneously
• Possibility of measuring mixed CW and pulsed sources

• Post processing data to reconstruct the time / amplitude of the measurements

• Pulse capture capability with Tau up to 500 ns using NHT 3DL meter and 1 µs using
NHT 3D and PRF up to 100 kHz
NHT 3D and PRF up to 100 kHz

The ER probes are based on diode sensors (detectors) and can measure both CW and pulsed signals in the L, S, C, X and Ku bands.

Application sectors:

• Air traffic control

• Coastal surveillance

• Meteorology

• Road traffic control

• Anti-collision

The measurement range of the probe makes it ideal for safety and permissible exposure limits in public and professional environments in accordance with the CEI 211-7/B standard.
