R&S
ZN-Z15
5
Operation
The external RFFE interface R&S ZN-Z15 is completely remote-controlled; it does
not provide any means for manual control.
The green LED and the orange LED on the rear panel indicate the availaility of
the regular 12V. If only the orange LED is lit this indicates insufficient input volt-
age.
The R&S ZN-Z15 is equipped with a 102x64 monochrome OLED-Display that dis-
plays the following information:
● Serial number of the instrument (for identification purposes)
● IP address
● USB and Direct Control link states
● Operational state of the instrument. This can be either
– OK if the instrument is error-free or
– ERROR <error code> with the error code of the last occurred error.
