R&S®HZ-9
Power Supply
At a glance
The R&S®HZ-9 power supply is a bipolar, constant
voltage source for the R&S®HFH2-Z2 and R&S®HFH2-Z6
active antennas, the R&S®ESH2-Z2 active voltage probe,
the R&S®EZ-12 antenna impedance converter and the
R&S®HZ-14 probe set for E and H near-field measurements
in situations where these instruments cannot be supplied
directly from a measuring receiver or when it is not pos-
sible to connect the instrument to the measuring receiver
(standalone operation). The R&S®HZ-9 power supply can
also be used in other applications.
The constant voltage source is designed as a low-noise
linear regulator and is ideal for EMI measurements in
shielded rooms. To allow direct connection of active instru-
ments, the 12-pin socket on the front panel is the same
type and has the same pin assignment as the sockets
on the front panels of the Rohde & Schwarz measuring
receivers.
