1.â 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 â50 dBm, zero set, zero
drift and noise effects can be disregarded.
2.â For U2041XA/42XA/43XA/44XA, specification is valid over a range of â45 to +26 dBm, DUT Max
SWR < 1.2. For U2049XA, specification is valid over a range ofâ45 to +20 dBm, DUT Max SWR
< 1.2. For all models, averaging set to 32, in Free Run mode. For power levels below â45 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.â With video bandwidth OFF setting and carrier frequency ⥠300 MHz.
4.â 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.
