LXI Class-C-Compliant Power Meter
A P-Series power meter is a LXI Class-C-compliant instrument,
developed using LXI Technology. LXI, an acronym for LAN eXten-
sion for Instrumentation, is an instrument standard for devices
that use the Ethernet (LAN) as their primary communicationinter-
face.
Characteristic information is representative of the product.
In many cases, it may also be supplemental to a warranted
specification. Characteristic specifications are not verified
on all units. There are several types of characteristic speci-
fications. These types can be placed in two groups:
Hence, it is an easy-to-use instrument especially with the usage
of an integrated Web browser that provides a convenient way to
configure theinstrument’s functionality.
One group of characteristic types describes ‘attributes’
common to all products of a given model or option. Exam-
ples of characteristics that describe ‘attributes’ are prod-
uct weight, and 50 ohm input Type-N connector. In these
examples product weight is an ‘approximate’ value and a
50ohm input is ‘nominal’. These two terms are most widely
used when describing a product’s ‘attributes’.
The P-Series power meters are supported by the Keysight Bench-
Vue software (version 3.0 and above). BenchVue makes it easy to
control your power meter to log data and visualize measurements
in a wide array of display options without any programming.
The second group describes ‘statistically’ the aggregate
performance of the population of products. These charac-
teristics 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 referred to as ‘typical’.
This software is available on the Keysight Instrument Control
DVD, which is included with each meter. You can download the
latest version of the software cost free at www.keysight.com/
find/BenchVue. Upgrading to the paid BenchVue Power Meter Pro
version (BV0007A) provides unrestricted data logging.
Specification Definitions
Conditions
There are two types of product specifications:
The power meter and sensor will meet its specifications
– Warranted specifications are specifications which are covered when:
by the product warranty and apply over 0 to 55 ºC unless oth-
erwise noted. Warranted specifications include measurement
uncertainty calculated with a 95% confidence.
– stored for a minimum of two hours at a stable tem-
perature within the operating temperature range, and
turned on for at least 30 minutes
– Characteristic specifications are specifications that are not
warranted. They describe product performance that is useful
in the application of the product. These characteristic specifi-
cations are shown in italics.
– the power meter and sensor are within their recom-
mended calibration period, and
– used in accordance to the information provided in the
User's Guide.

Average, peak and peak-to-average ratio power measurements are provided with free-run or time-gated definitions.
Time parameter measurements of pulse rise time, fall time, pulse width, time-to-positive occurrence and time-to-negative
occurrence are also provided.
Sensor compatibility
P-Series power meters are compatible with all Keysight Technologies, Inc. P-Series wideband power sensors, E-Series sensors,
8480 Series sensors and N8480 Series sensors1. Compatibility with the 8480 and E-Series power sensors will be available
free-of-charge in firmware release Ax.03.01 and above. Compatibility with N8480 Series power sensors will be available
free-of-charge in firmware release A.05.00 and above.
1. Information contained in this document refers to operation with P-Series sensors. For specifications when used with 8480 and E-series sensors (except
E9320A range), refer to Lit Number 5965-6382E. For specifications when used with E932XA sensors, refer to Lit Number 5980-1469E.
