JD746A
CellAdvisor™ RF Analyzer
Spectrum Analyzer: 100 kHz to 4 GHz
Cable and Antenna Analyzer: 5 MHz to 4 GHz
Power Meter: 10 MHz to 4 GHz
Specification Conditions
The JD746A 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
