FSH-Z44

The FSH-Z44 from Rohde & Schwarz is a 200MHz to 4GHz directional power sensor. The sensor provides simultaneous measurement of output power and matching of transmitter system antennas under operating conditions. It is used with the R&S FSH handheld spectrum analyzer for simultaneous measurement of forward and reflected power. The FSH-Z44 offers a frequency range from 200MHz to 4GHz and a measurement range from 30mW to 300W. The weight is 0.65Kg (1.43lb) and dimension (W × H × D) is 120mm x 95mm x 39mm.

• Less than 1.07 VSWR referenced to 50 ohm at 200MHz to 3GHz, less than 1.12 at 3GHz to 4GHz
• 120W to 1000W power handling capacity depending on temperature and matching
• Less than 0.06dB at 200MHz to 1.5GHz, les than 0.09dB at 1.5GHz to 4GHz insertion loss
• 30mW to 300W (CW, FM, PM, FSK, GMSK0), 30mW to 300W/CF (modulated signals) power measurement range
• 0.40%/K (0.017dB/K) at 200 to 300MHz, 0.25%/K (0.011dB/K) at 300MHz to 4GHz temperature coefficient
• 0.03W minimum forward power (specifications complied with ≥ 0.4W)
• greater than 30dB at 200MHz to 3GHz, greater than 26dB at 3GHz to 4GHz directivity
