7 GHz measurements

Agilent Technologies has introduced an enhanced bandwidth option for its Infiniium 54855A 6 GHz oscilloscope that allows engineers to increase the oscilloscope bandwidth to 7 GHz.

Agilent Technologies has introduced an enhanced bandwidth (EBW) option for its Infiniium 54855A 6 GHz oscilloscope that allows engineers to increase the oscilloscope bandwidth to 7 GHz.

When combined with the Agilent 1134A InfiniiMax probe amplifier and E2677A solder-in differential probe head, the system is claimed to be the industry’s first to enable real-time, high-impedance 7 GHz measurements.

The ability to make high-impedance measurements and probe multiple locations on a device under test is required for system debug, characterisation and optimisation of new high-speed digital product designs in the computer, communications and semiconductor industries.

The EBW option also allows engineers to reduce overall measurement system noise by lowering the oscilloscope’s bandwidth for improved accuracy and repeatability. Agilent’s proprietary digital signal processing techniques allow engineers to take advantage of the fundamental trade-off between bandwidth and system noise to optimise the measurement capability of the oscilloscope for specific measurements.

Until now, Agilent claims that engineers performing frequency domain analysis or measuring signals with low signal amplitudes had no simple method to reduce noise levels for a given bandwidth, single-event signal.

The high-bandwidth, Agilent InfiniiMax 1134A active probe amplifier with a differential solder-in probe head can match the 7 GHz capability of the new EBW option by providing a typical measurement bandwidth of 7 GHz to the solder-in probe tip. These flexible probe tips can be re-soldered from location to location, or multiple probe tips can be used on a single device under test.

The 7 GHz Enhanced Bandwidth option is priced at $5,000. The Agilent 54855A 6 GHz Infiniium oscilloscope is priced at $58,995, and the Agilent 1134A InfiniiMax active differential probe amplifier with the Agilent E2677A solder-in differential probe head is priced at $5,450.
