R&S NRP-Z11/21/31/41/61/211/221 Remote Control - Commands
1137.7470.12 6.15 E-7
SENSe:RANGe[?] 0 to 2 (1 for R&S NRP-Z211/221)
SENSe:RANGe selects the measurement path of the sensor.
The power sensor R&S NRP-Z11/21/31/41/61 has three separate measurement paths. Path 1 is the
most sensitive, path 2 medium and path 3 the least sensitive. SENSe:RANGe 0 selects path 1,
SENSe:RANGe 1 path 2 and SENSe:RANGe 2 path 3.
The power sensor R&S NRP-Z211/221 has two separate measurement paths. Path 1 is the more
sensitive, path 2 the less sensitive. SENSe:RANGe 0 selects path 1, SENSe:RANGe 1 selects path 2.
The dynamic ranges of these measurement paths depend on frequency and temperature and are
model-specific. Reference values are:
• (R&S NRP-Z11/21/31/41/61)
40 SW (–14 dBm) for the most sensitive measurement path, 4 mW (6 dBm) for the medium one and
400 mW (26 dBm) for the least sensitive;
• (R&S NRP-Z211/221)
380 SW (–4.2 dBm) for the more sensitive measurement path and 190 mW (22.8 dBm) for the less
sensitive one.
The query yields
• 0 for path 1,
• 1 for path 2,
• 2 for path 3.
If the measurement path is selected manually (SENSe:RANGe:AUTO OFF), the currently selected
measurement path is output. With automatic selection, the last path that was set manually is output.
Since this setting has been saved, it is immediately reset after deactivating the automatic function.
Default setting: 2 (NRP-Z11/21/31/41/61, least sensitive path) or
1 (NRP-Z211/221, less sensitive path)
SENSe:RANGe:AUTO[?] OFF | ON
SENSe:RANGe:AUTO ON activates the automatic selection of the measurement path and
SENSe:RANGe:AUTO OFF deactivates it.
The query yields
• 1 for OFF,
• 2 for ON.
Default setting: ON
SENSe:RANGe:CLEVel[?] –20.0 to 0.0
SENSe:RANGe:CLEVel is used to reduce the transition range between measurement paths 1 and 2 or
2 and 3 by the indicated value (in dB). This can improve the measurement accuracy for signals with a
high peak-to-average ratio, since the headroom for modulation peaks becomes larger. The
disadvantage is that the S/N ratio is reduced at the lower limits of the transition ranges.
The query yields the offset of transition ranges between measurement channels 1 and 2 or 2 and 3.
Default setting: 0.0 [dB]
SENSe:SAMPling[?] FREQ1 | FREQ2
SENSe:SAMPling is used to vary the sampling frequency of the analog-digital converter in the sensor.
With parameter specification FREQ1 the sampling frequency is 134.400 kHz, and 119.467 kHz with
