1) By default, the discrete RBW filter selection mode (1, 2, 3, 5, … steps) is active. Alternatively, steplessly variable RBW can be activated for RBW ≤ 20 MHz. The SNR in the variable RBW selection mode may be slightly lower than in the discrete RBW selection mode.
2) The sample rate is selected automatically.
3) This applies to resolution bandwidths ≤ 300 kHz. For larger RBWs, spurious frequency response contributions might violate these limits at certain RF input frequencies. In addition, RBWs using zero IF mode might violate these limits due to DC offset contributions.
4) Expanded uncertainty (k = 2) for absolute continuous average power measurements on CW signals centered within RBWs ≤ 10 MHz. Specifications include calibration uncertainty, aging, linearity and temperature effect. Measurement noise must additionally be taken into account when measuring low powers. The contribution of measurement noise can be neglected below a two-sigma value of 0.01 dB.
For signal power levels less than 30 dB above the DANL at the selected RBW, a measurement bias must additionally be taken into account.
For power levels above +15 dBm/–15 dBm for 30 dB/0 dB RF input attenuation, respectively, uncertainty contributions due to intermodulation and other nonlinear effects must additionally be taken into account. For RBWs below 1 kHz, LO phase noise contributions must additionally be taken into account. For RBWs above 300 kHz, uncertainty contributions due to coherent spurious response frequencies (e.g. when a locked reference frequency is used) must additionally be taken into account. When configuring the power sensor for use with an externally supplied LO signal, uncertainty contributions due to the signal integrity of the external LO signal must additionally be taken into account. Signal integrity includes properties such as frequency accuracy, and amplitude and phase stability
