Synchronizing Output Turn-on Delays
All N6700 Power Modules that are installed in a Keysight N6700
mainframe exhibit a minimum delay offset that applies from the time that
a command to turn on the output is received until the output actually
turns on. If you specify a user-programmed turn-on delay, this delay will
be added to the minimum delay offset, resulting in a turn-on delay that
is actually longer than the one you programmed. The minimum delay
offset is shown as follows:
Power Modules
Options and Mode
Delay Offset
N673xB, N674xB, N677xA Without relays 32 ms
With relay option 760 58 ms
N6751A, N6752A Without relays 25 ms
With relay option 760 51 ms
N6753A, N6754A Without relays 18 ms
With relay option 760 44 ms
N6761A, N6762A Voltage Priority - without relays 32 ms
Voltage Priority - with relay option 760 58 ms
Current priority - without relays 23 ms
Current priority - with relay option 760 45 ms
N6781A, N6782A, N6784A
Voltage Priority - Low Z mode; Current Priority 25.6 ms
Voltage Priority - High Z mode 24.8 ms
With relays always closed
Voltage Priority - Low Z mode; Current Priority 5.2 ms
Voltage Priority - High Z mode 7.3 ms
N6785A, N6786A Voltage Priority - Low Z mode; Current Priority 35.9 ms
Voltage Priority - High Z mode 34.9 ms
With relays always cl
osed
Voltage Priority - Low Z mode; Current Priority 5.2 ms
Voltage Priority - High Z mode 7.3 ms
To determine which power modules are installed in your mainframe,
select
System\About\Module
from the front panel. This identifies the
power module and the installed options. If N676xA power modules are
installed, send the OUTP:PMODE? query to determine if Current priority
mode has been set.
To determine the actual turn-on delay between the “on” event (such as
pressing the Output On key or sending an Output On command), you
must add the programmed turn-on delay to the minimum delay offset as
shown in the following example. In this example, if you program delay
values of 10 ms, 20 ms, 30 ms, and 40 ms for output channels 1 through
4 respectively, the actual output delays will be 68 ms, 45 ms, 81 ms, and
72 ms for output channels 1 through 4.
