Improved Level Linearity
Conventional spectrum analyzers use an analog IF and log amp to
achieve good level accuracy at points near the log scale reference
level, but the accuracy degrades at points that are further away.
The MS2830A uses a digital IF instead of a log amp, which
supports measurements with excellent accuracy at any point.
Example: Level Stability by Switching Reference Level
Dual Sweep Speed: Normal/Fast
When sweep time is set to [Auto], Normal (normal sweep) or Fast
mode (high-speed sweep) can be set. The Fast mode sweeps six
times faster than the Normal mode.

Level Linearity
The MS2830A total level accuracy is better than that of
conventional spectrum analyzers but sometimes a power meter
is used when wanting to measure with even higher accuracy.
However, use of a power meter narrows the dynamic range
and errors may also occur easily when switching the power
range. Since a power meter has no frequency selection, the
total power of the input signal is measured. In other words, the
power of the target frequency components cannot be
separated out.
Measurement can be performed with a wide dynamic range
after checking the MS2830A level measurement reference
value with a power meter.
The MS2830A total level accuracy includes:
• Frequency characteristics
• Linearity
• Attenuator switching error
And supports excellent:
• Log scale stability
Example of Sweep Mode Switch Error: (CW –10 dBm input)
