Series 8650A Universal Power Meters
4-10 Manual 31470, Rev. E, April 2001
NOTES:
1. Linearity Error (%) = [(R1/R2) / (P1/P2) - 1] x 100
2. Accumulated error is the sum of the current dB segment linearity error plus the previous accumulated error.
3. Use the first CW Linearity error value entered in the +16 dBm to +20 dBm Linearity Data on page 4-9.
Linearity Data - (-60 dBm to +16 dBm)
