Definitions
Product data applies under the following conditions:
• Three hours storage at the expected operating temperature followed by 30 minutes warm-up, unless otherwise stated
• Specified environmental conditions met
• Recommended calibration interval adhered to
• All internal automatic adjustments performed, if applicable
Specifications with limits
Describe warranted product performance by means of a range of values for the specified parameter. These specifications are marked
with limiting symbols such as <, ≤, >, ≥, ±, or descriptions such as maximum and minimum.
Specifications in normal print refer to parameters where compliance is ensured by the design or derived from the measurement of
related parameters.
Specifications in bold print are 100 % tested. Test limits have been narrowed by guard bands to take into account measurement
uncertainties, drift and aging, if applicable.
Specifications without limits
Describe warranted product performance by means of a representative value for the specified parameter. Limits are omitted whenever
they are not relevant for the specification (e.g. dimensional data).
Typical values (typical)
Represent the population mean for the given parameter, derived from the design and/or production testing. Typical values are not
warranted by Rohde & Schwarz.
Limits of uncertainty
Expanded uncertainties with a coverage factor of 2, calculated from the test assembly specifications and the modeled behavior of the
sensor, including environmental conditions, aging, wear and tear, if applicable. The given values represent limits of uncertainty that are
met by the Rohde & Schwarz instrument after calibration at a production or service site. Limits of uncertainty are indicated in italics
and have been determined in line with the rules of the Guide to the Expression of Uncertainty in Measurement (GUM).

Table B Noise reduction factors for gating and smoothing
The noise reduction factors in this table describe how measurement noise is reduced if the mean value of adjacent samples is taken
over a time interval. The time interval can be the length of a gate, timeslot, or pixel in trace mode. Without averaging or for single
events, use the leftmost column. If averaging is activated, use the columns for the individual repetition rates and additionally apply
multipliers from table C. The repetition rate is identical to the frequency of the measurement being carried out, i.e. the inverse of the
trigger period.

Example: A power measurement on a radar pulse is carried out by means of the Timeslot/Gate function. The gate length is set to 1 µs,
and the averaging number to 32. The pulse repetition rate is 100 Hz, and the measurement is performed at +15 °C ambient
temperature. The pulse power is about –10 dBm.
From the specifications, a 2σ noise-per-sample value of 2 µW (typical) can be derived for reference conditions. Applying a multiplier of
1.1 from table A for +15 °C ambient temperature and –10 dBm pulse power results in 2.2 µW sampling noise under measurement
conditions. Gating reduces noise by a factor of 0.15 (table B), and averaging further reduces noise by a factor of 0.18 (table C). The
residual 2σ noise of mean power within the gate can then be calculated as follows: 2.2 µW × 0.15 × 0.18 = 59 nW (0.06 % of
measured value).

Footnotes
1
Specifications apply to timeslots/gates with a duration of 12.5 % referenced to the signal period (duty cycle 1:8). For other waveforms, the following
equation applies: lower measurement limit = lower measurement limit for Continuous Average mode / √(duty cycle).
2
With a resolution of 256 pixels.
3
Specifications apply to the default transition setting of 0 dB. The transition regions can be shifted by as much as –20 dB using an adequate offset
4
To prevent aliasing in the case of signals with discrete modulation frequencies between 100 kHz and 1 MHz.
5
Time span prior to triggering, where the trigger signal must be entirely below the threshold level in the case of a positive slope and vice versa in the
case of a negative slope.
6
Specifications expressed as an expanded uncertainty with a confidence level of 95 % (two standard deviations). For calculating zero offsets at higher
confidence levels, use the properties of the normal distribution (e.g. 99.7 % confidence level for three standard deviations).
7
Specifications apply to zeroing with a duration of 4 s. Zeroing for more than 4 s lowers uncertainty correspondingly (half values for 16 s).
8
Within one hour after zeroing, permissible temperature change ±1 C, following a two-hour warm-up of the power sensor.
9
Two standard deviations at 10.24 s integration time in Continuous Average mode, with aperture time set to default value.
The integration time is defined as the total time used for signal acquisition, i.e. the product of twice the aperture time and the averaging number.
Multiplying the noise specifications by (10.24 s/integration time) yields the noise contribution at other integration times. Using a von Hann window
function increases noise by a factor of 1.22.
10
Expanded uncertainty (k = 2) for absolute power measurements on CW signals with automatic path selection and a user-defined transition setting of
0 dB. Specifications include calibration uncertainty, linearity and temperature effect. Zero offset, zero drift and measurement noise must additionally be
taken into account when measuring low powers. As a rule of thumb, the contribution of zero offset can be neglected for power levels above –35 dBm
for the R&S
®
NRP-Z11/-Z21/-Z31/-Z91, –25 dBm for the R&S®NRP-Z22/-Z92 and –15 dBm for the R&S®NRP-Z24. The contribution of measurement
noise depends on power and integration time and can be neglected below 0.01 dB.
Example: The uncertainty of a power measurement at 3.2 nW (–55 dBm) and 1.9 GHz is to be determined for an R&S
temperature is +29 ºC and the averaging number is set to 32 in the Continuous Average mode with an aperture time of 20 ms.
Since path 1 is used for the measurement, the typical absolute uncertainty due to zero offset is 64 pW (typical) after external zeroing, which
corresponds to a relative measurement uncertainty of

record the entire series of measurements when triggered by a single event. In this case, the power sensor automatically starts a new measurement as
soon as it has completed the previous one.
