1 About the R&S HA-Z24E
The R&S HA-Z24E is an RF preamplifier with a specified frequency range from
1 GHz to 85 GHz with a nominal gain of 20 dB. It can be used up to 90 GHz
(overrange).
The R&S HA-Z24E allows you to measure signals from devices under test with
low output power, using measurement devices which feature a low sensitivity and
do not have a built-in RF preamplifier.
The R&S HA-Z24E is a stand-alone product which can be used with any kind of
test setup that provides two USB 2.0 host interfaces. The interfaces are used to
provide both the DC supply voltage and the control interface for the preamplifier
via a Y-shaped cable.
Each R&S HA-Z24E is characterized in the factory regarding both magnitude and
phase. The S-parameters measured in the factory up to 90 GHz are stored in the
internal EEPROM of the preamplifier. The S-parameters can be used to compen-
sate the magnitude and phase characteristics of the preamplifier in the test setup.
The S-parameters can be read out of the preamplifier via USB into an S2P file,
which can then be used for the compensation algorithms. As soon as you connect
the R&S
HA-Z24E to a power supply, the preamplifier is permanently on.
