Safety Rules
Careful observance of the VDE safety instructions is essential!
Only fuses with the same power-down characteristics are to be used!
On feeding in signals, heed the allowable peak levels!
• HF input: max. 120 dBµV (60 dBmV)!
• Do not connect direct-current (DC) voltage to the RF socket!
Do not connect low frequency alternating-current (AC) voltage to the RF
socket!
The instrument is also energised when disconnected!
Use only the power supply unit provided for voltage feed!
Depending on the programming, between 5 V and 20 V may be
connected to the RF input socket. From 10 V to 20 V, up to 500 mA can
be obtained from the source, and up to 100 mA can be obtained from 5 V
to 9.9 V.
