Expert Mode
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.
For Receiver and Transmitter Test Configuration
HS Gears
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
Nominal Data Rate
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.
Nominal Ref. Clock
For the selected reference clock frequency, the generated data rate is calculated as a multiple of the
reference clock.
Additional Gears
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.
