NOISE POWER RATIO1

NPR

10 dB tilt, 6 dB offset at 1026 MHz, total composite

power (TCP) = 67 dBmV

10 dB tilt, no offset, TCP = 67 dBmV

0 dB tilt, 6 dB offset at 1026 MHz, TCP = 67 dBmV

1 The noise power ratio gives an equivalent result to the standard modulation error rate (MER) testing but with improved dynamic range using an industry-accepted method.
