德国罗德与施瓦茨 R&S®ESH3-Z6 V-Network

R&S ESH3-Z6 V-Network
For measuring disturbance voltage and susceptibility in low-impedance power supply networks.

**At a glance**
The R&S ESH3-Z6 single-phase V-network with a simulating impedance of 5 μH // 50 Ω meets the requirements of EN55025/CISPR25 as well as MIL-STD-461, DEF-STAN 59-411, and DO-160 in the frequency range from 100 kHz to 200 MHz.
The R&S ESH3-Z6 is rated for a continuous current of up to 100 A and can handle surges of up to 500 A for a maximum of 30 s.
The R&S ESH3-Z6 V-network comes with a calibration report for the voltage division factor.

**Design**
The R&S ESH3-Z6 V-network has screw terminals with a large contact area for low-impedance connection to the equipment under test (EUT) and the power supply using cable lugs. Plastic covers on both connections protect against accidental contact.

**Key facts**
- Frequency range: 0.1 MHz to 200 MHz
- Continuous current: Up to 100 A
- Calibration in line with CISPR25:2016 (Edition 4)
- Note: The current MIL-STD-461 standard requires an impedance of 5 μH // 50 Ω. A possible alternative for CE101 and CE102 testing is 5 μF // 50 Ω, e.g. for smaller platforms (power distribution less than 50 m) such as fighter aircraft.
