A precision fixed termination (or load) consists of an immovable, (fixed) termination which, when mated to the end of a trans-mission line or cable, absorbs nearly all of the signal energy traveling toward it. An ideal “matched” condition exists when a termination with an impedance value of Z0, is connected to the end of a transmission line or cable that also has a characteristic impedance of Z0. Such an ideal “matched” condition (one with no mismatch between the termination and its mated line or cable) is critical if a voltage standing wave ratio (VSWR) of 1.0:1 is to be achieved in a system with a 50 or 75 ohm impedance value. Simply put, the more closely the 1.0:1 ratio is approached, the more accurate the measurements that can be made from a system.

• Uses modern optical pumping instead of older magnetic cesium methods, which improves long-term stability and reliability while measuring many more atoms for highly accurate timing.
• Offers excellent frequency accuracy (≤ ±1×10⁻¹²) and very low phase noise on multiple frequency outputs (5 MHz, 10 MHz, 100 MHz), making it suitable for precise synchronization.
• Supports multiple power options (AC, DC ±24 V, DC −48 V) with redundant and hot-swappable supply modules and optional battery backup for one hour, aiding uptime in critical environments.

• Dual-channel and differential voltage measurements
• 1% accuracy at full scale
• True RMS response below 30 mV
• Optional low-frequency probe for measurements from 10 Hz to 100 MHz
• DC recorder output
• IEEE-488 interface standard, RS-232

The 9240 series is the latest addition to the popular 9200 series of RF voltmeters. It combines accuracy, smart probes, and operator features that have never before been available in its price range. It is simple to use on the bench, and comprehensive enough to integrate into an ATE system. Boonton’s proven voltage probes directly measure from 200 μV to 10 V with usable indication as low as 50 μV and have true RMS response below 30 mV.
