Item Information string Remarks
"MANUFACTURER" "Rohde & Schwarz" Manufacturer
"TYPE" "NRP-Z5x" for R&S NRP-Z5x Type designation
"STOCK NUMBER" "1138.0005.03" for R&S NRP-Z51
"1138.0505.02" for R&S NRP-Z52
"1138.2008.03" or
"1138.2008.04" for R&S NRP-Z55
"1171.8201.02" for R&S NRP-Z56
"1171.8401.02" for R&S NRP-Z57
"1173.7031.02" for R&S NRP-Z58
Material number
"SERIAL" "<serial number>" 6-digit serial number
"HWVERSION" "000000001" Hardware version
"HWVARIANT" "000000010" Hardware variant
"SW BUILD" "<build number>" Version number of sensor firmware
"TECHNOLOGY" "Thermal" Detector technology used
"FUNCTION" "Power Terminating" The R&S NRP-Z5x is a terminating power sensor.
"MINPOWER" "<nominal lower test limit in W>" The nominal lower test limit is 300 nW, i.e. with s-parameter
correction deactivated, the sensor returns the information string
"3e-7" as a response to SYSTem:INFO? "MINPOWER". With
s-parameter correction activated, the information string
depends on the nominal lower limit of the sensor/twoport
combination.
"MAXPOWER" "<nominal upper test limit in W>" The nominal upper test limit is 100 mW, i.e. with s-parameter
correction deactivated, the sensor returns the information string
"0.1" as a response to SYSTem:INFO? "MAXPOWER". With s-
parameter correction activated, the information string depends
on the nominal upper limit of the sensor/twoport combination.
"MINFREQ" "<min. measuring frequency in Hz>" The minimum measuring frequency is 0 Hz, i.e. the sensor
returns the information string "0" as a response to
SYSTem:INFO? "MINFREQ".
"MAXFREQ" "<max. measuring frequency in Hz>" The maximum measuring frequency is 18 GHz for the
R&S NRP-Z51, 33 GHz for the R&S NRP-Z52, 40 GHz for the
R&S NRP-Z55 Mod. 03, 44 GHz for the R&S NRP-Z55 Mod. 04
50 GHz for the R&S NRP-Z56, 67 GHz for the R&S NRP-Z57,
or 110 GHz for the R&S NRP-Z58, i.e. the sensor returns the
information string "1.8e+10", "3.3e+10", "4e+10", "5e+10",
"6.7e+10", or "1.1e+11", respectively, as a response to
SYSTem:INFO? "MAXFREQ".
"IMPEDANCE" "50"
The RF input has a nominal input impedance of 50 .
"COUPLING" "DC" The RF input is DC-coupled.
"CAL. ABS." "<date>" Date of absolute calibration in the format YYYY-MM-DD.
Calibration Date" is returned with an invalid date entry.
"CAL. REFL." "<date>" Date of reflection-coefficient calibration in the format YYYY-MM-
DD. "Invalid Calibration Date" is returned with an invalid date
entry.
