SZI 30
The SZI 30 is a small area emitter which can be fed modulated signals from an SI 30 or any
other wideband modulator. It has no charging compartments, the LED on the right of the
front panel serves as a power indicator instead, showing that a supply voltage is present.
At the back of the SZI 30 you have—besides the DC input connector—two RF sockets. If
no plug is connected to the output socket, a 50 Ω terminating impedance is switched into
the RF connection.

Any wideband infrared modulator
