CellAdvisor™ Signal Analyzer

Spectrum Analyzer: 100 kHz to 4 GHz

Power Meter: 10 MHz to 4 GHz

Specication Conditions

e JD748A specications apply under these conditions:

• e instrument has been turned on for at least 15 minutes

• e instrument is operating within a valid calibration period

• Data with no tolerance are considered typical values

• Cable and antenna measurements apply aer calibration to the OSL standard

• Typical and nominal values are dened as:

– Typical: expected performance of the instrument operating under 20° to 30°C

aer being at this temperature for 15 minutes

– Nominal: a general, descriptive term or parameter
