"FUNCTION"
"Power Source"
The R&S NRP-Z28/-Z98 is a power sensor that functions as a
source.
"MINPOWER"
"<nominal lower test limit in W>"
The nominal lower test limit of the R&S NRP-Z28/-Z98 is
200 pW, i.e. with s-parameter correction deactivated, the
sensor returns the information string "2e-10" 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 of the R&S NRP-Z28/-Z98 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"
"1e+07" or "9e+03"
The minimum measuring frequency is 10 MHz for the
R&S NRP-Z28 and 9 kHz for the R&S NRP-Z98.
"MAXFREQ"
"1.8e+10" or "6e+09"
The maximum measuring frequency is 18 GHz for the
R&S NRP-Z28 and 6 GHz for the R&S NRP-Z98.
"RESOLUTION"
“2.5
S
s Ext, 10
S
s Int”
The maximum time resolution that can be reached in the
Trace
mode is 2.5
S
s for internal triggering and 10
S
s for external
triggering.
"IMPEDANCE"
"50"
The RF input has a nominal input impedance of 50 .
"COUPLING"
"AC/DC"
The RF input is DC-coupled, but DC voltages superimposed on
the RF signal are suppressed by the measurement amplifier.
"CAL. ABS."
"<date>"
Date of absolute calibration in the format YYYY-MM-DD. "Invalid
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.
