Product Description
1- 6 CSA8000B & TDS8000B User Manual
H 80E04 -- A dual-channel, 20 GHz TDR sampling module. The TDR step
generator provides 35 ps reflected step risetime. Voltage polarity can be
reversed on either step to provide true differential TDR.
H 80E06 -- A single-channel, 70+ GHz sampling module. This model provides
very high performance bandwidth for general-purpose characterization of
high speed devices and circuits.
Other Modules.
H 80A01 Trigger Prescale Limiting Preamplifier Module -- A single-channel
module providing 8-14 GHz AC coupled 50
Ω limiting preamplification. It
increases the sensitivity of the prescale trigger input of the 8000 Series
instruments to
≤200 mV
pk-pk .
H 80A02 EOS/ESD Protection Module -- A module that protects the sensitive
input stage of instruments (such as the sampling bridge of Tektronix
electrical TDR sampling modules) from damage due to electro-overstress
(EOS) and electro static discharge (ESD) from the device under test (DUT).
