Parameter Description
Calibrations and tests can be conducted beyond the limits and constraints of the CTS; the test
parameters used in the calibration and test procedures are shown and can be modified by the user.
The following HS-Gears are available:
• GEAR 1-A
• GEAR 1-B
• GEAR 2-A
• GEAR 2-B
• GEAR 3-A
• GEAR 3-B
• GEAR 4-A
• GEAR 4-B
The selection of gears is not limited. If "x" number of gears are selected, the HS terminated and
non-terminated tests are available "x" times, in respective test sub-groups.
For receiver test, GEAR 3-A and 3-B are only available for spec. 3.10 and 4.10. GEAR 4-A
It sets the reference clock frequency to achieve the nominal Gear x-B data rate value as given in the
specification. In case of custom data rates, the reference clock is adjusted to achieve the HS custom data
rate.
For the selected reference clock frequency, the generated data rate is calculated as a multiple of the
reference clock.
PWM Gear 1 is always tested. Additionally, PWM Gears from Gear 2 to Gear 7 can be selected.
The selection of gears is not limited. If "x" number of gears are selected, the PWM terminated and
non-terminated tests are available "x" times, in respective test sub-groups.
This option is only visible for PWM device type.
Select the version using the drop down menu:
• 3.10
• 4.10
The frequency can be chosen as follows:
• 19.2 MHz
• 26 MHz
• 38.4 MHz
• 52 MHz
Brings up a dialog where the voltage levels and the default values can be selected. Refer to Default
Levels for more details.
Brings up a dialog where the timing parameters (Prepare Length, Stall, Sleep, Sync Length) can be
defined. Refer to "Default Timing"
Brings up a dialog where the HS, LS, and Squelch sequence files can be selected. Refer to
Sequences" for more details.
