Anritsu field portable 40 GHz vector voltmeter

Click2Contact

Anritsu has introduced a vector voltmeter mode (VVM) option for its Microwave Site Master S820E that enables the S820E to be used as a drop-in replacement for legacy vector voltmeter instruments. With the ability to provide full A/B and B/A ratio capability without additional and expensive VNA options, the S820E with the VVM provides users with a compact and cost-efficient single-instrument solution to make key field measurements when deploying or maintaining wireless networks.

The Site Master S820E combines performance, functionality, reporting and durability to meet the most demanding field-testing requirements. It provides handheld field vector voltmeter measurements specified to 40 GHz. When using the A/B and B/A ratio capability, a unique Auto-tune feature allows the S820E to successfully lock onto an external reference source signal that can be as much as ±100 kHz away from the selected tuned frequency, without having to widen the measurement IFBW or establish common 10 MHz reference time-base signals. Input sensitivity for either the A or B reference receiver ranges automatically from +5 dBm to -60 dBm, surpassing the range of traditional vector voltmeters. A Reference Signal Detection message advises users when the instrument successfully locks onto the external source signal when making A/B and B/A ratio measurements. The message is displayed at the bottom of the display in bright green.

The S820E can measure 1 DUT or the user can select a table display format, which allows up to 12 DUTs to be displayed simultaneously. All 12 DUT measurements may be made relative to a stored reference measurement. Reflection and/or transmission measurements made in VVM mode may be vector error corrected via the calibration process and do not require an external CW source or bridges, couplers or splitters.
