PROCEDURE:
Figure 4. Three filters combined in Analyzer Channel 1
Function 1 (First
measurement parameter)
Function 2 (Second
measurement parameter)
11. Function 1 indicates the rst measurement parameter and Function 2 indicates the second measurement
parameter.
(Figure 4 shows that Function 1 refers to Frequency measurement while Function 2 refers to Vac measurement).
12. Press [Function 1] to select Frequency, Vac, or Vdc measurement parameter.
13. Press [Function 2] to select Frequency, Vac, Vdc, SNR, Noise Level, SINAD, THD+N Ratio, THD+N Level,
X-talk (Crosstalk), SMPTE, DFDs, and Phase measurements.
14. Press [Units] to select the measurement engineering unit for Function 1 and Function 2 measurement.
15. Press [Analyzer Settings] to select Coupling, Detector, Filter, Input Type, and Range settings.
– Press [Coupling] to select AC or DC coupling.
– Press [Detector] to select RMS, QPK, or Peak to Peak detector.
– Press [Filter] to select None, LP (Low Pass), HP (High Pass), or Weighting lters.
– Press [Input Type] to select Balance or Unbalanced input.
16. To show the different lters, combine the LP, HP, and Weighting lters in one analyzer channel.
– Press [Filter] > [LP] and select 15 kHz.
– Press [HP] > 22 kHz.
– Press [Weighting] > A-Weighting.
– The 15 kHz and 22 kHz will create a bandpass lter. Create an A-Weighting lter in the bandpass lter
(see Figure 4).
Note: You can combine a maximum of three different lters, that is, one lter from each lter category.
– Before proceeding to the next demonstration, “Loop Test”, clear the lter by pressing [Filter] > [None].
Press [Rel/Ref] for ratio measurement.
17. Press [Rel/Ref] for ratio measurement.
18. To show the Generator and Analyzer on the same display screen, press [Display/Mode] under the
System panel (see Figure 5).
