A.H. Systems Model PAM-0118 Pre-Amplifier

Most common causes of failure:

• Excessive power applied to the RF input (such as ESD to the input

• Improper connection sequence (sequence such as application of signals to

• Excessive DC voltage applied

• Storage near strong EMI or RFI fields

• Loose connections causing intermittent events

An over voltage at the preamp input will damage the preamplifier. This type of

damage is without fault of A.H. Systems and will void the warranty.

To connect:

1. Apply DC Voltage

2. Connect output load

3. Apply RF input

To disconnect:

1. Remove RF input

2. Remove load

3. Remove DC voltage
