terminated with two Narda Model 375BN–M loads, or equivalent.
RF Termination/Load
 100 W non–radiating RF load ; used (as required) to provide dummy
RF loading during BTS transmit tests.
Miscellaneous RF Adapters, Loads, etc
 As required to interface test cables and BTS equipment and for
various test set ups. Should include at least two 50 Ohm loads (type
N) for calibration and one RF short, two N–Type Female–to–Female
Adapters.
High–impedance Conductive Wrist Strap
 Motorola Model 42–80385A59; used to prevent damage from
Electrostatic Discharge (ESD) when handling or working with
modules.

interface test equipment to the BTS receive and transmit antenna
inputs during optimization/ATP or general troubleshooting
procedures.
Optional Equipment
Frequency Counter
 Stanford Research Systems SR620 or equivalent. If direct
measurement of the 3 MHz or 19.6608 MHz references is required.
Spectrum Analyzer
 Spectrum Analyzer (HP8594E with CDMA personality card) or
equivalent; required for tests other than standard Receive band spectral
purity and TX LPA IM reduction verification tests performed by the
LMF.
Local Area Network (LAN) Tester
 Model NETcat 800 LAN troubleshooter (or equivalent); used to
supplement LAN tests using the ohm meter.
Span Line (T1/E1) Verification Equipment
 As required for local application
RF Test Cable (if not Provided with Test Equipment)
 Motorola Model TKN8231A; used to connect test equipment to the
BTS transmitter output during optimization or during general
troubleshooting procedures.
