5.6.6 [View]
Stops updating trace data and display current trace for observation..
5.6.7 [Operations►]
Enter trace math related sub menu.
1) [1 ↔ 2]
Exchange the trace stock 1 data with trace stock 2 and place them in display mode.
2) [2-DL → 2]
Deduct display line value in trace stock 2. This function execute once when activated. Press [2 - DL → 2] again to execute it
the second time. When this function activated, display line will also be activated.
3) [2 ↔ 3]
Exchange the trace stock 2 data with trace stock 3 and place them in display mode.
4) [1→3]
Exchange the trace stock 1 data with trace stock 3 and place them in display mode.
5) [2→3]
Exchange the trace stock 2 data with trace stock 3 and place them in display mode.
5.7 [Detector]
While displaying a wider span, each pixel contains spectrum information associated with a larger subrange. That is, several
samples may fall on one pixel. Which of the samples will be represented by the pixel depends on the selected detector type.
Press this key to pop out the relevant menu includes [Pos Peak], [Neg Peak], [Normal], [Sample], [RMS Avg], [Voltage Avg],
[Quasi-Peak].
Key points:
•
Selects an appropriate type according to the application in order to ensure the accuracy of the measurement for your
application.
• When [BW/AVG]→[EMI Filter►]→[EMI Filter] is On, [Quasi-Peak] is available.
Table 8 1 Detector type comparison
Detector Type
Measurement
Pos Peak
Positive peak detector ensures that no peak signal is missed, which is useful for measuring signals that
are very close to the base noise.
Neg Peak
Negative peak detector is used in most cases with the self-test of the spectrum analyzer and is rarely
used in the measurement. It is able to restore the modulation envelope of the AM signal well.
Normal
Display pos peak and neg peak alternately when noise is detected, or it only display pos peak.
Sample
Sampling detector is conducive to measurement noise signal. Compared with the standard detection
method, it can measure noise better.
RMS Avg
RMS Average detector averages rms levels to calculate the true average power. It is best for measuring
the power of complex signals.
Voltage Avg
Voltage Average detector averages the linear voltage data of the envelope signal measured during the
bucket interval. It is useful for observing rise and fall behavior of AM or pulse-modulated signals.
Quasi-Peak
Quasi-peak detector is a weighted form of peak detection. The measured value drops as the repetition
rate of the measured signal decreases. It is used in EMI testing.
