5.28 Delay Measurement
With the "Delay" measurement function it is possible to determine the delay time
between analog signals. When the measurement starts, the observed signals must
have a low level; therefore a suitable sample signal would be, for example, the burst
signal generated by the R&S UPP. The time until the "Audio Trigger Threshold" is
exceeded is measured. To achieve a short rise time, work with signals of the highest
possible frequency and a high bandwidth (80 kHz in the generator and analyzer).
Refer to
This menu item determines the signal to which the delay is referenced. If this signal is
missing or its level is too low, the measurement cannot be carried out.
"Trigger IN
(BNC)"
The reference time is when there is a positive TTL level at the rear
BNC socket, which is labeled with "TRIGGER IN". The delay time of
all switched-on audio channels is referenced to this time.
"Ref Channel" The reference time is when the "Audio Trigger Threshold" of the
selected reference channel is exceeded. The delay time of the other
switched-on audio channels is referenced to this time.
