Learn to power ON and OFF the VNA.

LCD Touchscreen

VNA is equipped with a 12.1-inch TFT color, touch-sensitive LCD screen for displaying traces, scales, settings, softkeys and other measurement related information. The touchscreen LCD allows to manipulate softkeys by touching the LCD screen directly. For more on the LCD touchscreen, see Screen Display Tour.

Note:

Do not press the surface of the LCD touchscreen with a sharp object (e.g., a nail, pen, or screwdriver). Pressing the surface with a sharp-pointed object will damage the LCD screen surface or cause the screen to fail.

Valid pixels are 99.998 % and more. Below 0.002 % of fixed points of black, blue, green or red are not regarded as failure.

Test Ports

The models are available with 2 or 4 test ports.

See Specs for more information about the Test port connectors and Input damage levels.

The LED of each test port shows the source output status. When the signal comes from the port, its LED is lighted.

Front panel Access Jumpers

These connectors provide direct access to the VNA source and receivers. This allows you to make a wide variety of measurements and improve dynamic range.

See front panel jumpers specifications

Port 1	Port 3	Port 4	Port 2

N5247B

Port 1 and Port 3 SW SRC OUT - COMB IN jumpers moved from rear-panel (J8 through J11) to front-panel to minimize path loss.

Important: All of the N5247B front-panel jumpers are EXTREMELY FRAGILE. Learn more.

USB Hub

This USB hub contains four USB ports to power your VNA peripherals. There are also four USB ports on the rear panel.

Limitation: The total power consumption for all eight USB ports is limited to 4.0 amps. If this limit is exceeded, all USB ports are disabled until a device is removed and power consumption falls below the limit. When first connected, Keysight ECal modules 8509x and N4431 draw significantly more current than other modules.

Note:

The FIRST TIME each USB device (ECal module, power sensor, and so forth) by serial number is connected to a specific VNA USB port, you must be logged in to the VNA with an Administrator account. Learn how.

When a New Hardware Found dialog appears, click OK to install the device.

After being installed, when that same USB device is connected to that same USB port, you can be logged in to the VNA with a Limited/User account.

Ground terminal

Connect a banana-type plug to this terminal for grounding to the VNA chassis.

No probe power

Probe power is NOT provided on VNA models. Learn more about Active Probing
