Requirements for the external DC power supply
The following specifications should be used to ensure the optimum performance:
DC Supply voltage
+12 to +36 VDC, 2 Amps
Line regulation +/- 0.05 % for a 10 % line change
Load regulation +/- 0.05 % for a 50 % load change
Output ripple < 5 mV peak-to-peak
Pin configuration Same as RM12BRD-6PH(71) DC connector on the back panel
Verify that the connector of the DC power supply has the correct pin configuration. Do not
apply AC voltage to the DC power connector. Failure to follow these directions may cause
injury or death to personnel, cause irreparable damage to the instrument and voids all
warranties.
2.2 Instrument Safety and Preparation for Use
The HPDA-15RMi-CW is designed to distribute RF signals with a frequency of 1 to 100
MHz. The recommended level for the RF input signal is 0 dBm to +15 dB.
Input signals must be kept below +20 dBm as greater power levels will damage the unit
and void all warranties. The HPDA-15RMi-CW RF outputs are DC isolated from the
chassis ground to prevent ground loops. These outputs are rated to a maximum of 50 V.
Absolute Maximum Ratings
Input RF Power +20 dBm Maximum
Reverse RF Power +20 dBm Maximum
Voltage at the RF Input +50 V Maximum
Voltage at the RF Output +50 V Maximum
Storage Temperature -10 to +75 ºC
Operation Environment 0 to +50 ºC
