•
Check All /Uncheck All: selects/deselects all the available coupling parameters on all channels (4
channel and 8 channel models only).
•
Press the parameter checkbox to select/deselect the single coupling parameter.
•
When waveforms have different carrier shapes, only the common parameters will be available
on this page.
•
When a change of a parameter of Channel 1 causes an out of range error on the coupled
channel, the application will limit the parameters value to the latest valid ones.
•
When a change of the Ratio or Offset value you try to insert causes an out of range in the
coupled channels, the Ratio and Offset values will be set automatically to the previous valid one.
•
The application may need to recalculate new parameter ranges due to a change in the user
interface (such as carrier waveform type, other waveform parameters, run mode etc.).
In these cases, if the parameter is coupled but the Ratio and the Offset no longer meet the
coupling condition, the parameter coupling will be automatically disabled.
For example, select a Sine Waveform on CH1 and CH2, set a frequency of 350 MHz on CH1 and
coupling frequency with Ratio 1 and Offset 0. The result will be a Sine Waveform on CH2 with a
frequency of 350 MHz.
If you change on the CH2 the carrier waveform from Sine to Square, the Frequency range will be
recalculated (the Square cannot reach 350 MHz of maximum frequency) and the frequency
coupling will be disabled.
•
If you press the Copy Ch N Button while the coupling channel is active, only the parameters that
are not coupled will be copied to the other channels.
Example: Frequency Coupling
1. Suppose that the channel 1 has a frequency of 1 MHz.
2. Set the Channel 2 coupling button to ON and the coupling parameters will appear
3. Check the Frequency parameter
4. Set Ratio to 2.5 and Offset to 0
5. The Channel 2 frequency will be 2.5 MHz
Now the channel 1 and the channel 2 frequency parameters are coupled and on the Channel 2 Carrier
page, the Frequency parameter textbox will be disabled.
On the contrary, the Channel 1 frequency parameter is still enabled and if you then change the
frequency to 5 MHz, the channel 2 frequency will automatically change to 12.5 MHz.
Now if you set the Offset to 1 MHz the coupling equation will be:
CH2 Frequency = Channel1 Frequency*2.5 + 1 MHz and changing channel 1's frequency will change
