In this case, set Parameter 31 - TX Use 230 kHz BW on Data Dev [1=yes] to 0 to reduce the measurement bandwidth, or turn off the other radio. By setting the Spectrum Analyzer Span to 0.
Reference Specifications (Pass/Fail Limits) Specifications (Pass/Fail Limits) The Test Software uses the entries in the TESTS (Pass/Fail Limits) screen to determine if a measurement meets the test requirements. If not, it displays a “fail” indication in the results display (and, in some instances, provides for adjustments and re-test). This section lists the specification limit names and explains how each is used.
Reference Specifications (Pass/Fail Limits) 7. AMPS SAT Frequency Error Enter the upper and lower limits, in Hz. The Test Software measures the difference between the measured SAT frequency and the SAT frequency specified in the Base Station Configuration Menu, and compares the result with the limits. When testing all SAT frequencies, the Test Software changes the SAT frequency to measure each frequency in sequence, using the same frequency error limits for all measurements. 8.
Reference Testing without MSC Control Testing without MSC Control Chapter 4, “Performing Tests,” on page 59 lists the steps for fully automated testing, using the Test Software to control the Base Station. The steps of that chapter use a PC to control the Base Station via the MSC. If you are using a Test Set setup with no PC and connection to the MSC, the following considerations apply: • Make certain to set the Send Control Commands to MSC field on the Base Station Configuration Menu to NO.
Reference Using a PC Card Using a PC Card Before a PC card may be used for the first time, it must be initialized. The following tow sections describe the initialization process and offer some troubleshooting information in the event of a problem with the use of a PC card. Initializing a PC Card Step 1.
