1Introduction
Product Overview
The N8262A P-Series Modular Power Meter, LXI Class C compliance instrument is
an upgrade of P-Series Power Meter. It is developed using LXI Technology. LXI, an
acronym for LAN eXtension for Instrumentation, is an instrument standard for
devices that use the Ethernet (LAN) as their primary communication interface.
When using the N8262A, a virtual user interface runs on a Windows based
controller will give you manual control over the operation of the power meter. This
interface is emulated from the P-Series Power Meter’s soft front panel display
where Standard Commands for Programmable Instrumentation (SCPI) commands
exist to access desired functionality.
N8262A operates with three software: Web Browser Interface, P-Series Soft Front
Panel and Synthetic Instrument Finder. It offers identical measurement
performance as P-Series Power Meter. Operation of the N8262A occur by using a
virtual panel hosted on PC or via the remote programming interface: Soft Front
Panel. It provides robust instrument control and works with the environment you
choose.

Make sure you have gone through the Installation Guide before you proceed.
Power Meter and Sensor Capability
Your P-Series Modular Power Meter is compatible with Keysight P-Series,
E-Series E9300, E-Series E4410 and the 8480 Series Power Sensors. However,
not all sensor and meter combinations have the same features or capabilities. The
main differences are as below:

Average power of modulated signal * * *
Peak power *
Cal factors stored on EEPROM * * *
200 readings/sec * * *

The E-Series and 8480 Series Power Sensors require N1917A/B/C/D cables
when connected to the P-Series Modular Power Meters.
Specifications
The specifications for the power meter are listed in Chapter 5, “Specifications and
Characteristics,” starting on page 139.

NOTE
These softkeys are located to the left of the display.
Make sure you have connected to the P-Series Soft Front PaneI before you
proceed. You may refer to Installation Guide for details.
This section briefly describes the functions of the soft front panel softkeys.
Introduction 1
Key Function
Click this softkey to preset the power-meter. An option list of pre-installed
measurement configurations is presented. Select an option and click the confirm
softkey.
Click this softkey to select the upper or lower measurement window. The selected
window is highlighted by a blue line on the right side of the window. Any measurement
setup you create is performed in the selected window.
Click this softkey to choose windowed, expanded, or full-screen display of a numeric
measurement. It also provides quick access to the Gate Control screen and menu when
a trace window is selected.
Click this softkey to switch off the soft front panel

These softkeys are located to the left of the display.
Key Function
Click this softkey to access general configuration-menus, such as IP address.
You can also access the Self-Test and Table entry menus. The measurement
screen remains visible.
Click this softkey to access the channel configuration menus. Channel
parameters such as averaging and offsets are configured from this menu.
Click this softkey to access the triggering menu. Unless a P-Series Sensor is
connected, all the menu softkeys are disabled (grayed out).
Click this softkey to setup relative measurements or set display offsets.
Use this softkey to configure the selected measurement.
Click this softkey to access the measurement display menu. You can choose
the displayed measurement resolution, units and display format.
Use this softkey together with to configure measurement
displays.

Key Function
These softkeys are all associated with the menu labels and data entry. They
are located to the right of the display.
Click this softkey to return to the previous screen. This softkey also cancels pop-up
entry.
Introduction 1
These softkeys are referred to by the text on the display next to them.
For example, during a Preset, you are given an option to confirm the command. Click to
continue, that is, click the softkey beside the displayed word ‘confirm’.
This softkeys is used when there is a two page menu to be displayed. For example, a
1of2 is displayed beside the softkey indicating the first page of a two page menu.
Click the softkey to access the next page or second page. (A 2 of 2 is displayed).

These softkeys and connectors are associated with the measurement
channels and are located on the right-hand side of the soft front panel.
Key Function
The arrow softkeys are used for navigation around the parameter entry
screens. The up and down arrows are used for selecting values from a pop-up
list, they can also be used for stepping two values, X Scale and Y Scale. They
are also used to enter text, for example, table names. The arrow softkeys are
presented individually as , , and .
