1. Any relative power measurement of up to 5 dB will have <1% error, excluding zero set, zero drift and noise effects. With default aperture and averaging, for
power levels above –50 dBm, zero set, zero drift and noise effects can be disregarded.
2. For all USB/LAN peak and average power sensor except U2049XA, specification is valid over a range of –45 to +26 dBm, DUT Max SWR < 1.2. For
U2049XA, specification is valid over a range of–45 to +20 dBm, DUT Max SWR < 1.2. For all models, averaging set to 32, in Free Run mode. For power levels
below –45 dBm, the effect of zero drift, zero set and measurement noise have to be considered separately base on the uncertainty calculation method
shown in Appendix A.
3. With video bandwidth OFF setting and carrier frequency ≥ 300 MHz.
4. Five MHz video bandwidth is applicable for carrier frequency ≥ 300 MHz. For carrier frequency < 300 MHz, video bandwidth of LOW/MED is 90 kHz, video
bandwidth of HIGH/OFF is 240 kHz. Refer to Characteristic peak flatness section for details.
