STEP TRACE:
In step trace mode, the PMDPro varies the PMD along the selected curve
using a constant, user-selected step size and dwell time per point. The setup
screens for step trace mode are as follows:
Use the up and down arrows to move between scan setup options and the
ENTER key to access the setup screen for the selected option.
Options a-e are the same as for continuous trace mode.
g. DWELL:
_ _50 ms
↑
(STEP TRACE ONLY)
e. MODE: BI-DIREC
↑
f. STEP SIZE: _ _0.4 ps
↓
c. STEP DIRECTION: UP
↑
d. CYCLES: _ _10 Count
↓
a. START (stp TRACE)
↓
b. Rng: _0.00, 64.4 ps
f.
STEP SIZE:
Set the DGD step size between points, in ps. Use the left and right arrows
to move between digits and the up and down arrows to increment the
selected digit. The minimum step size is 0.1 ps. The maximum step size is
determined by the range selected in option b). The ENTER key selects the
displayed value.
g.
DWELL time:
Set the dwell time at each point, in ms. Use the left and right arrows to
move between digits and the up and down arrows to increment the
selected digit. The dwell time range is 1 to 9999 ms. The ENTER key
selects the displayed value.
5.
DGD-PMD Emulation:
This is the statistical PMD emulation function. The PMDPro generates a
Maxwellian distribution of DGD values with a user-selected number of points and
average DGD. The SOPMD can either be zero (first-order PMD emulation only)
or can be a statistical distribution corresponding to the generated DGD.
When this option is selected, the following screen is displayed:
