Pulse Profile Measurement
Required Equipment
This application sheet describes the use of an R&S ZVA vector analyzer and an
R&S ZVAX24 extension unit for creating a pulsed RF signal and performing pulse profile measurements.
1.1 Required Equipment
The pulse profile measurement can be carried out with the following equipment:
● Network analyzer (NWA) R&S ZVA24 with a firmware version V2.60 or higher and
a motherboard part number 1305.6470.02 (see "Info > Hardware Info ...")
● Option R&S ZVA-K27, "Pulse Generator"
● Option R&S ZVA-K7, "Pulsed Measurements"
● Option R&S ZVA24-B16, "Direct Generator/Receiver Access" at source port 1
● One R&S ZVAX24 extension unit equipped with option R&S ZVAX24-B271, "Pulse
Modulator Generator Port 1"
1.2 Measurement Principle
The pulse modulator option R&S ZVAX24-B271 provides a pulsed source signal at the
NWA port 1. Pulse width and period are determined by the used pulse generator,
which can e.g. be the internal pulse generator of the NWA provided by option
R&S ZVA-B27. This option also provides a second "Sync" signal that can be used to
synchronize the measurement to the rising edge of the generated pulses.
The DUT is connected between the test ports 1 and 2 of the analyzer; the transmitted
pulsed signal is measured at port 2 using the analyzer's "Pulse Profile" mode.
The measurement involves the following steps:
1. Connecting the extension unit
2. Configuring the extension unit for the selected measurement and test setup
("ZVAX Path Configuration")
3. Defining the pulse generator and the trigger settings
4. Configuring the "Pulse Profile" mode
5. Calibration
6. Connecting the DUT and measuring
Power calibrations and system error corrections for test setups with an extension unit
can be performed in the ordinary way.
