Description: Wireless Mobile & Base Station Test Sets HP 8921A HP 8921A Cell Site Test Set 1 The HP 8921A cell site test set is a highly-portable, integrated solution for the installation and maintenance of AMPS and TACS cell sites and is upgradable to test CDPD, CDMA, and TDMA systems. The HP 8921A incorporates more than twenty powerful instruments into a compact, 38-pound package. The integral IBASIC controller in the HP 8921A runs the HP 11807B cell site test software to fully automate base station test and adjustment procedures. Automation combined with accurate mea surements increases technician efficiency to speed installation and maintenance procedures. HP 8921A Features Summary • AM/FM signal generator • AM/FM modulation analyzer • Duplex offset generator • RF power meter • RF frequency counter/frequency error meter • Audio frequency counter and power meter • AC/DC voltmeter • SINAD/SNR/distortion meter • Two variable frequency AF generators • Digital oscilloscope • Built-in IBASIC controller • Spectrum analyzer with tracking generator • Adjacent channel power meter • Signaling encoder and decoder • High-stability timebase • DC current meter • GPIB/RS-232/parallel remote interfaces • Upgradability to TDMA, CDMA, or CDPD • Optional cellular base station test software • Optional Amps cellular phone test software • Optional radio interface card • Optional Ericsson PCM reference Upgrading for New Formats Beyond testing analog AMPS and TACS base stations, the HP 8921A is ready to grow with your measurement needs for digital cellular systems with upgrades available for: • TDMA • CDMA • CDPD High-Performance Spectrum Analyzer The spectrum analyzer of the HP 8921A has the wide dynamic range and synthesized frequency accuracy previously found only in expensive stand alone spectrum analyzers. Wide dynamic range allows the HP 8921A to locate low level signals in the presence of high power transmitters. Synthesized frequency accuracy translates into high confidence that you’ve located the correct signals. With frequency spans ranging from 1 GHz to as narrow as 5 kHz, the HP 8921A has the flexibility to look at the entire RF spectrum and then zoom in on the desired signals. The marker function displays the frequency and amplitude of any displayed signal. The marker-to-peak function displays the frequency and amplitude of the largest on-screen signal with a single keystroke. Built-in Tracking Generator The HP 8921A spectrum analyzer also includes a built-in tracking gener ator for tuning base station duplexers. With +13 dBm power output (over range), use the tracking generator as an input stimulus to the duplexer. The calibrated level of the spectrum analyzer ensures accurate adjust ment of duplexers. Using the marker function of the spectrum analyzer, the rejection of the duplexer can be measured at any point of the filter response. Antenna return loss can be quickly and accurately measured onsite with the HP 8921A tracking generator. Using the tracking genera tor to drive the antenna through an external VSWR bridge, the reflected power can be measured on the HP 8921A spectrum analyzer. Other measurements performed with the tracking generator include insertion loss and frequency response of filters, cables, or attenuators. The track ing generator features calibrated output level from –137 to +7 dBm and variable frequency offset for IF to RF conversion measurements. Coupled with 1, 2, and 10 dB per division spectrum analyzer ranges, nor malization, and marker capability, the tracking generator makes the HP 8921A ideal for all types of measurements and adjustments.

Graphical displays show connec tion diagrams and highlight key adjustment points when required. Technicians spend less time learning and more time testing with the HP 8921A cell site test set. Another software package, the HP 11807B Option 120, provides AMPS system information. The software uses the HP 8921A to scan for and decode local control channels, display system data, and measure
