Applications
Extending the
PNA-X to
millimeter-wave
frequencies
PNA-X’s unique hardware architecture provides:
• Two- and four-port solutions for measurements on a wide variety of single-ended and
balanced millimeter-wave devices
• True-mode differential measurements at millimeter-wave frequencies using two internal sources
• Fully integrated solution for millimeter-wave pulse measurements using built-in pulse
modulators, pulse generators, and receiver gates
• Accurate leveled power at millimeter-wave frequencies with advanced source-power
calibration methods
• Direct connection of terahertz modules driven by a 50 GHz PNA-X
• Single-sweep network analysis from 10 MHz to 110 GHz with full power-level control,
using the 67 GHz PNA-X and millimeter-wave extension modules
Two- and four-port configurations
Four-port system architecture
Four-port single sweep 10 MHz to 110 GHz
The N5262A millimeter-wave test-set
controller connects four millimeter-wave
test modules to the PNA-X. For two-port
measurements, the N5261A millimeter-
wave test-set controller is available.

coherent source control of OML modules using the
N5262A millimeter-wave test-set controller.
PNA-X-based 110 GHz systems come in
two- and four-port versions, with power-
level control, true-differential stimulus, and
the ability to measure frequency converters
with SMC. These systems are table-top
replacements for 8510XF systems, with
superior performance.
Direct connection of VDI modules to a
50 GHz PNA-X enables S-parameter
measurements to 1.05 THz.
