CT6 Current Probe

The CT6 is the ne west addition to the Tektronix portfolio of high-frequency

current probes. It is designed to meet the needs of high-speed circuit

design and test applications which require ultra-high bandwidth, low

inductance, and extremely s mall form factor. The CT6 provides up to

2 GHz bandwidth when used with high-bandwidth oscilloscopes such as

the Tektronix TDS69 4C, TDS794D, and TDS7000 Series oscilloscopes or

with other compatible 50 Ω inp ut measuring instruments. L ow inductance

(<3 nH) assures that the loading effect of the CT6 on the circuit-under-test

will be negligible, which is e specially important for today's low-amplitude,

high-speed circuit designs such as disk drive read/write preampliﬁers. The

probe is a closed-circuit design which will accept uninsulate d wire sized

up to 20 gauge. This product is exempt from CE mark by virtue of its 30 V

voltage limit.

CT1/C

T2 Current Probes

The CT 1 and CT2 Current Probes a re designed for permanent or

semi-

permanent in-circuit installation. Each probe consists of a current

transformer and a n interconnecting cable. The current tra nsformers have

a small hole through which a current carrying conductor is passed during

circuit assembly.

The P6 041 Probe Cable provides the connection between the CT1 and CT2

Current Transformers and a BNC oscilloscope input. A 50 Ω termination

is required to terminate the cable when conne ct ed to a high-impedance

(1 MΩ) o scilloscope input. One probe cable can be used to monitor several

curr

ent transformers that have been wired into a circuit.

The CT1, CT2, and CT6 normally operate directly into 50 Ω scopes and other measuring device inputs. The CT1 or CT2 can be used with 1 MΩ input systems; use the P6041 probe cable and terminate the output with a 50 Ω feed-through termination (see Optional Accessories).
