Attention!
The service functions are not necessary for normal measurement operation. However,
incorrect use can affect correct operation and/or data integrity of the R&S ZVL.
Therefore, many of the functions can only be used after entering a password. They are
described in the instrument service manual.
Input RF/Cal/TG
Selects the source signal for the RF input path in spectrum analysis mode (with option R&S ZVL-K1).
• RF switches the RF path to the input connector for spectrum analyzer mode (PORT 2). The R&S
ZVL measures the RF input signal fed in via PORT 2.
• Cal switches the RF path to the internal calibration source (65.8333 MHz; see Comb Frequency)
and activates the data entry of the output level of the calibration source. Possible values are 0 dB
and –30 dB.
• TG is for future extensions.
The Input RF/Cal/TG softkey is available in spectrum analyzer mode only.
Comb Frequency
Opens a dialog box to set the comb generator frequency for the internal calibration (see Input Cal):
• Comb/1: 65.8333 MHz / 1
• Comb/64: 65.8333 MHz / 64
• Comb/65: 65.8333 MHz / 65
The Comb Frequency is available in spectrum analyzer mode only, provided that Input Cal is active.
Reset Password
Deactivates all set passwords.
