RSA2203A & RSA2208A User Manual
The setup display area in the upper part of the screen shows the analyzer
hardware settings (see Figure 2--10). The contents differ depending on the
measurement mode: spectrum analysis (S/A), modulation analysis (Demod), or
time analysis (Time), as shown in Table 2--3.

Item Description Mode
Frequency Indicates the center frequency. All
Span Indicates the span.
Input Att
.
Indicates the attenuation of an input signal
before it enters the internal mixer.
RBW Indicates RBW (Resolution Bandwidth) for
compatibility with swept spectrum analyzers.
Refer to FFT and RBW on page 3--101.
S/A
NBW Indicates NBW (Noise Bandwidth) instead of
RBW when FFT-processed data does not go
through RBW process.
Trace 1 and 2 Indicates the Trace 1 and 2 trace type.
Spectrum Length Indicates time length of a 1024-point FFT frame.
It is determined by the span.
Real Time S/A
Spectrum Interval Indicates time interval between FFT frames.
Refer to FFT Start Point on page 3--104.
Acquisition Length Indicates time to acquire a block of data.
It can be set in the Timing menu.
