LED Description
Unlock When this LED is lit, the frequency entered for the external clock
does not match the actual input from the external clock. In this
state, the internal PLL is not locked and the instrument's outputs
may not be within specification.
You have to either reenter the frequency of the external clock, or ex-
ecute the Measure function. See “Clock Sources” on page 75 for
details.
Active When lit, indicates that the instrument is either in external or direct
external clock mode. A valid external clock signal has to be applied
to the clock input.
If not lit, the internal clock source is used.
Armed Indicates that the instrument is waiting for a signal at the Start In-
put.
When the specified signal arrives, the instrument starts generating
signals.
Port LEDs Indicate the status of the port. When the LED is lit, the port is
active.
