EMI-PREAMP Tektronix

Preamplifier for Tektronix EMC pre-compliance EMI-PREAMP (Com-Power PAM-103 offered by Tektronix) Key features Wide frequency range (1 MHz to 1 GHz) Internal battery or AC adapter operation (>13 hours per charge) High gain, low noise figure (33 dB Gain (typical)) (3.3 dB noise figure) Individual calibration included The EMI-PREAMP preamplifier is intended for improving measurement system sensitivity during EMC compliance testing. With a frequency range of 1 to 1000 MHz and a gain of 33 dB, it amplifies the signals that were previously hidden below the noise floor of the EMI receiver so that they can be seen and measured. The preamplifier has a gain variation of 3 dB for the entire frequency range to reduce measurement errors. It can be powered by the rechargeable NimH batteries included when an external power source is not available. www.tek.com 1Datasheet Specifications Preamplifier Frequency range 1 MHz 1 GHz Preamplifier gain 33 dB (3 dB) Linear RF input range < -30 dBuV 89 dBuV POUT at 1 dB compression 18.3 dBm POUT at 3 dB intercept (IP3) 32 dBm Noise figure < 3.3 dB Input sensitivity -30 dBuV (< 31.6 nV) RF input/output ports 50 N-type (female) Return loss (RF input/output 29.5 dB (minimum), 44 dB (average) ports ) 2 www.tek.com
