Test conditions:
• Temperature range: 10 °C to 40 °C.
List of test equipment:
PC with Windows 2000 or XP
HMI600 software
PC Ù P4LT cable 1:1 serial RS-232
Tx tuning adapter P3LL HENF209668
Rx tuning adapter P4LM HENF209665
RF test cable 50 Ohm V9MW, BNC to
SSMB (mini coax), 2 cables required
1KHL015238R0001
Level meter, wide band or selective,
10 kHz to 1 MHz.
Preferably 50 Ohm input, 75 Ohm may also
be used
SPM-33A (Acterna) or equivalent;
featuring both wide band as well as
selective measurements
Plastic tuning screwdriver
Notes:
• Level measurements during tuning & checking frequency response of P4RX are relative. Hence any ordinary
wide band or selective level meter with a frequency range 10 kHz to 1000 kHz can be used. Normally a wide
band level meter will be sensitive enough. If more sensitivity is required, use a selective one. Be careful when
using a wide band meter, as unwanted signals may disturb the measurement.
• The same Rx tuning adapter P4LM used for ETL 41 and ETL500 can be used for ETL600. However, if two
shorting wires are present on the P4LM, they must be removed. The position of these 2 shorting wires - if
present - will be across C1-C9 & C2-C10, under the sub-board.
