Page 3: Introduction
A.H. Systems Model PAM-0118 Pre-Amplifier INTRODUCTION The PAM-0118 broadband preamplifier is an excellent choice for improving system dynamic range. The performance of this preamplifier will increase your system sensitivity by at least 35 dB and is ideal for low-amplitude test measurements. -
Page 4: Intended Purposes
HAZARDOUS RF VOLTAGES The PAM-0118 preamplifier is reliable when operated under specified conditions; however the use of sensitive, high-performance semiconductors causes the preamplifier to be susceptible to ESD and EOS. The risk of damage due to ESD is small, but possible, because the charged object would have to come in contact with one of the center conductors. -
Page 5: Range Of Environmental Conditions
• 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. -
Page 6: Operating Instructions
OPERATING INSTRUCTIONS Operation of the Model PAM-0118 preamplifier is quite simple. The unit is turned on by first plugging the phone-type plug from an external power supply into the power input connector. The power supply is then plugged into the appropriate line voltage supply. -

Page 9: Conversion Formulas
For Immunity measurements, the generated electric field strength can be calculated by: FS = Approximate Field Strength in (V/m) P = Power in watts g = Numeric Gain d = Distance in meters © A.H. Systems inc. – April 2009 REV B... - Page 10 The derivation for the constant in the above equation comes from the decibel equivalent of the factor of 1000 used to convert W to mW and vice versa, as shown below. © A.H.
