The following sections cover mostly hardware and service-related topics.

12.1 Firmware installation

Upgrade versions of the analyzer firmware are supplied as single executable setup

files (*.exe).

64-bit only

Since version 3.00 of the analyzer firmware, 32-bit Windows is no longer supported.

Only 64-bit firmware is available.

To upgrade your instrument to 64-bit Windows 10, contact Rohde & Schwarz service.

Admin account

You need administrator rights to install a new firmware. See note on "User accounts

and password protection" on page 30 for details.

To perform a firmware update:

1. Copy the setup file to any storage medium accessible from the analyzer. This can

be either the internal mass storage drive, an external storage medium (USB mem-

ory stick, external CD-ROM drive) or a network connection (LAN).

The default name of the internal drive is C:. External storage devices are automati-

cally mapped to the next free drive, i.e. D:, E: etc.

Run the setup file from the Windows

Explorer. Follow the instructions of the setup

wizard.

Setup files can be reinstalled.

Factory calibration

A firmware update does not affect the factory calibration.

Downgrade to a firmware version < 3.00

To downgrade the firmware from a version ≥ 3.00 to a version < 3.00, it is required to

uninstall the firmware using Windows 10 "Apps & features" (Windows 7 "Programs and

Features") before proceeding with the installation.
