Description
These methods and properties provide access to data sheet specified and typical, max and min power levels (in dBm). Max power refers to the maximum leveled source power at the specified port. Min power is calculated by subtracting the power sweep range from the max leveled power. This information is stored by frequency band in a power specification file. This object provides access to the file’s contents and provides an interface to configure the port number and RF signal path of interest.
Power data is available as either the most restrictive value across a range of frequencies (when RangeGetMaxPower and RangeGetMinPower are used) or for discrete CW frequencies (when DiscreteGetMaxPower and DiscreteGetMinPower are used).
No measurement of instrument-specific dynamic range is performed; all power levels are equivalent to power data published in device data sheets. Power levels are valid only for measurement configurations where the front panel jumpers are in their standard positions, as originally shipped. Internal source attenuation and any calibrated external path loss/gain due to cables, fixtures, switches or booster amplifiers are not included in the reported min/max leveled power values. It remains the users’ responsibility to transform the reported factory power range data to a value corresponding to the specific calibration plane of their setups.
The power range data files contain both specified min/max leveled power values and the corresponding “typical” values. Some paths, that are not part of the specifications of the instrument may only have typical data. Only the “Specified” power range data is guaranteed for an instrument with an up-to-date calibration certificate.
