Extreme measurement
eficiency
The advantages are clear when per-
forming time interval analysis based on
zero dead time, time-to-data-converter
(TDC) technology. Extreme efficiency in
memory use and data transfer can be
achieved by eliminating the dead time
when measuring pulsed RF signals.
By storing only the precise times for
rising and falling edges of the RF pulse,
the PAS makes optimal use of the 4M
event memory in the Keysight TDC.
The dual memory architecture of this
TDC supports unrestricted time capture
length at rates as high as 1M events
per second. Extreme accuracy and time
resolution of 50 ps is achieved inde-
pendent of time record length. The PAS
system provides a wide bandwidth,
2 channel RF input reference module
(IRM) with built-in detectors and an
ultra low noise/low jitter 10 MHz ref-
erence oscillator. This IRM combines
all of the necessary signal routing, TDC
clock and 10 MHz reference outputs.
These features along with the flexible
internal and external triggering func-
tions allow you to synchronize the PAS
and other measurement instruments
with your RADAR system operation.
Time interval analysis using
the Keysight pulse analyzer
system
For applications focused on time inter-
val analysis of RADAR signals, use the
PAS system to make measurements
such as:
– RF pulse width (PW) versus time
– RF pulse repetition interval (PRI or PRF)
versus time
– PW and PRI histograms and statistics
(min/max, mean, std deviation)
– Raw time interval data and frequency
versus time data
– Flexible internal and external triggering
functions
– Markers and zooming features
