3.1.4. Configuration Replication
The
Copy Settings
operation is also found in various PSA Interactive menus and sub-menus. This window offers the
ability to quickly copy a type of configuration to one or more other ports in the currently addressed PSA chassis. When
the menu is opened
(see Figure 3.6)
, check boxes for every available test port will be enabled while unpopulated slots
will be disabled (grayed-out). A
Copy
field in the lower left of this menu shows the type of configuration parameters
that will be duplicated across all selected ports. The
Copy
field is strictly derived from the sub-menu where the
Copy
Settings
button was activated. Under the
Copy
field is the slot/port from where settings will originate. This is
equivalent to the current slot/port that was active when
Copy Settings
was selected.
If the
Copy Settings
button was pressed in the
Port (Detection) Configuration
menu, then only the port configurations
of ALT, Polarity, and passive detection Resistance/Capacitance will be duplicated across all selected ports. The actual
replication occurs upon pressing the
Copy Settings
button in the PSA Port Replication menu. The
DONE
button then
closes the window and returns to the menu that spawned it.
The
ALL PORTS
checkbox causes the current configuration settings to be duplicated to all available slots with
separate selections for each port. Replication will
occur across the entire PSA Instrument including
the multiple chassis’ that would make up a PSA-
2400 system.
When
Copy Settings
is invoked from the
Load
Configuration
menu, both static and transient
(
PSA-1200 only
) load configuration values will be
replicated to all selected test ports. When invoked
from the
PSA-1200
meter resource menus, the
respective meter configuration (trigger mode,
period, and timeout) will be replicated across all
selected ports.
3.1.5. Trigger Configuration
The
Trigger Configuration
resource menu
(Figure 3.7)
allows configuration and state control of the PSA waveform
trigger, also referred to as Trigger 1 or “
trig1
”. (
See Section 2.3.2 for further discussion regarding triggers
.) The
internal waveform trigger is derived from transitions on the PoE bus where both the edge-sense and the level may be
specified by the user. This trigger in turn may be used to trigger voltage measurements, load current measurements,
and load current transients.
The edge sense may be selected as either
Rising
or
Falling
. The trigger level may
take a value between 0 and 64 VDC with
granularity of 0.25 V. When a trigger level
is entered into the level entry field, it will be
automatically rounded to the neared 250 mV
increment when the [Enter] key is pressed or
Apply Settings
is pressed.
Apply Settings
causes the configuration to
be updated in the test port. It will
not be
updated
unless
Apply Settings
is pressed.
The
Apply Settings
button will annunciate
via red text that a change has been selected
and must be applied.
Read Settings
will
cause the current trigger settings from the
selected slot-port to be displayed in the
menu.
A new feature available with future PSA test blades will improve noise immunity of the PSA edge trigger allowing for
Normal
and a
Noisy
trigger processing modes. Normal mode will add 0.125 volts of noise tolerance to the edge
triggering action.
Noisy
mode will add 0.5 volts of noise tolerance meaning leading and falling edges can be properly
resolved in the presence of 500mV of random superposed noise on the edge. When connected to PSA-1200 Test Ports,
the
Noisy
checkbox will be inhibited.
