This chapter describes some topics that are only needed occasionally, or if a special
instrument configuration is required.
7.1 Firmware installation
Upgrade versions of the analyzer firmware are supplied as single executable setup
files (*.exe).
Admin account
You need administrator rights to install a new firmware. See note on "User accounts
and password protection" on page 19 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.
2.
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.
However, for a R&S ZNA that was factory calibrated with a firmware version < 2.0, an
upgrade to a firmware version ≥ 2.0 makes the factory calibration slightly less accurate.
A changed signal path in firmware versions ≥ 2.0 can result in an offset of approxi-
mately 0.3 dB for uncalibrated wave measurements. Calibrated measurements are not
affected. The offset can be eliminated by a new factory calibration at Rohde&Schwarz
service.
Downgrade to a firmware version < 1.90
Instruments shipped with a REFBOARD version > 001_000_000 cannot be downgra-
ded to a firmware version < 1.90 simply by executing the related firmware setup file.
Please contact R&S service if you plan such a downgrade.
