<Loop>
loop sweep
When start from <Single> sweep, SE2031 does an internal frequency sweep according to the settings of users.
After that, the status jumps back to <Stop> automatically.
When start from <Loop> sweep, SE2031 does constant loop sweep until users switch the status to <Stop>
manually.
3.2.6 < Harmonic>: Setting the Harmonic Detection
The harmonic setting interface is shown in Fig.21.
Fig.21 <Harmonic> Secondary Submenu
<Harmonic 1>
Setting harmonic 1. The minimum value is 1 and the maximum value is 32767.
<Harmonic 2>
Setting harmonic 2. The minimum value is 1 and the maximum value is 32767.
Input the order of the harmonic from keyboard. The display is 1 in default and this means detecting 1 order
harmonic (fundamental wave). The limitation of the harmonic setting is (Harmonic * Freq) < 3MHz, where Freq
means the reference frequency. Once beyond the limit, system will reduce the order of harmonic automatically to
meet the conditions. At the same time, when the order is set to 0, the system set the order to 1 automatically.
For example, the input signal is 1kHz square wave. Suppose that the signal’s amplitude is A. Set <Harmonic>as 1,
2, 3, 4, 5, 6…, the R will be 0.45A, 0.015A, 0.09A, 0…respectively. This sequence is A times higher the
coefficient sequence of the square wave Fourier Series.
It is necessary to set <List> in the <Full> option of the <Display> submenu during detecting double harmonic.
3.2.7 < Sine Output>: Setting the Sine Output
SE2031 can output sine wave whose amplitude range is from 0.001Vpp to 10Vpp through the “Sine Out” BNC
connector on front panel. <Fixed> fixed amplitude output, <Linear> linear sweep amplitude output or <Log>
logarithm sweep amplitude output can be set in submenu. There are <Sweep Type> <Voltage> <Sweep Set> and
