JD785A
CellAdvisor™ Base Station Analyzer
Spectrum Analyzer: 9 kHz to 8 GHz
Cable and Antenna Analyzer: 5 MHz to 6 GHz
Power Meter: 10 MHz to 8 GHz
Specification* Conditions
The JD785A specifications apply under these conditions:
• The instrument has been turned on for at least 15 minutes
• The instrument is operating within a valid calibration period
• Data with no tolerance are considered typical values
• Cable and antenna measurements apply after calibration to the OSL standard
• Typical and nominal values are defined as:
–
Typical: expected performance of the instrument operating under 20° to 30°C
after being at this temperature for 15 minutes
–
Nominal: a general, descriptive term or parameter
