条件：characteristics are shown in italics or denoted as “typical,” “nominal” or “approximate.”
Characteristic specifications are not warranted. They describe product performance that is useful in the
application of the power sensors by giving typical, but non-warranted performance parameters. These
Characteristic information is representative of the product. In many cases, it may also be supplemental
Characteristic specifications are not verified on all power sensors. The types of characteristic
specifications can be placed in two groups
条件：a 50‑Ω input is nominal. These two terms are most widely used when describing a product’s
• The first group of characteristic types describes ‘attributes’ common to all products of a given
model or option. Examples of characteristics that describe attributes are product weight and
50‑Ω input Type‑N connector. In these examples, product weight is an approximate value and
• The second group of characteristic types describes ‘statistically’ the aggregate performance
of the population of products. These characteristics describe the expected behavior of the
population of products. They do not guarantee the performance of any individual product. No
measurement uncertainty value is accounted for in the specification. These specifications are
The power meter and power sensor meet their specifications when:
• Stored for a minimum of two hours at a stable temperature within the operating temperature range
and turned on for at least
30 minutes
• The power meter and power sensor are within their recommended calibration periods
• Used in accordance to the information provided in the power meter’s user’s guide
条件：Specifications stated hereon refer to all N8480 Series power sensors, unless otherwise stated. The term
“standard” refers to all N8480 Series sensors except Option CFT.

The N8480 Series power sensors (excluding Option CFT) have two measurement ranges: a lower
power range and an upper power range. The power meter automatically selects the proper power level
range. To avoid unnecessary switching when the power level is near the switch point, switching point
hysteresis has been added
N8481A/82A/85A/87A/88A and N8486AQ/AR power sensors
This hysteresis causes the lower power range to remain selected until approximately
–0.5 dBm as the
power level is increased. Above this power, the upper power range is selected. Likewise, the upper
power range remains selected until approximately
–1.5 dBm as the signal level decreases. Below this

Calibration factor and reflection coefficient
条件：meters automatically read the CF data stored in the sensor’s EEPROM and use it to make the corrections.
The reflection coefficient (Rho or ρ) relates to the SWR according to the following formula:
Maximum relative measurement uncertainties of the calibration factor (CF) are listed in the following table.
1. The characterized calibration factor should not deviate between periodic calibrations by more than the specified maximum relative
maximum uncertainty. √2 ∗UUUUUUUU with a reference calibration factor of 100%.
Calibration factor (CF) and reflection coefficient (Rho) data are unique to each sensor. The CF corrects for
the frequency response of the sensor. The Keysight EPM Series, EPM-P Series, and P-Series power
There is only one set of CF data used for both the high and low range of each sensor. The uncertainty
analysis for the calibration of the sensors was done in accordance with the ISO Guide. The uncertainty
data reported on the calibration certificate is the expanded uncertainty with a
95% confidence level and a
coverage factor of 2.
