12 Test Receiver ¸ESPI
Specifications
Specifications apply under the following conditions: 15 minutes warm-up time at ambient
temperature, specified environmental conditions met, calibration cycle adhered to and total
calibration performed. Data designated "nominal" applies to design parameters and is not
tested. Data designated "
 = xx dB" indicates the standard deviation.
