Highest Resolution TDR/TDT Measurements
High TDR resolution is essential for accurately characterizing
complex high-speed structures. With TDR step 10-90 rise time
as fast as 6 ps and receiver bandwidths of 50 GHz, the DCA-TDR
solution resolves the magnitude and location of impedance
discontinuities with unmatched performance.
The flexible, upgradable design offers 2- and 4-channel remote head
modules.
The importance of TDR edge speed
TDR resolution is determined by the rise time of the TDR step
generator, the bandwidth of the receiver and the effective
dielectric constant of the device under test (DUT).
The edge speed that is delivered to the DUT is called the
transmitted edge speed. It is measured at the output of the
remote head by a high-bandwidth receiver.
10 to 90% edge speed (raw hardware
performance):
–– 35 GHz option: < 18 ps
–– 50 GHz option: < 7 ps
–– See specification table for details
10 to 90% edge speed (with TDR calibration):
–– 35 GHz option: 15 ps, characteristic
–– 50 GHz option: 6 ps, characteristic
–– See specification table for details
The ultra-fast TDR step generator (raw hardware step shown above)
provides industry-leading TDR resolution.
Upgradable to protect your investment:
Bandwidth upgrades:
Upgrade a 35 GHz module to 50 GHz by ordering the appropriate
N1055AU option.
Channel count upgrades:
Upgrade 2 channels to 4 channels by ordering the appropriate
N1055AU option.
All upgrades require returning the N1055A to Keysight
Technologies.
