LED Meter Probe allows the user to take Real time Phase Angle readings along with AC nominal voltage readings. A PD800W LED Meter Probe works in conjunction with the Receive Unit to verify phase identification along with the actual phase angle data. This is all done without any calculations or data transfer from the field to a base computer. The meter probe and reference probe or receive unit can operate at 100 feet of separation and up to 300 feet line of sight separation. In the event that this distance would need to be greater, the Receive Unit can be unplugged from the charging cable and taken into the field while operating on it's rechargeable batteries for up to 8 hours at a time.

Phase Noise Testers / Signal Source Analyzers
7000 Series
-
Berkeley Nucleonics Corporation
The 7000 series is an all-in-one integrated solution that offers an indispensable set of low-noise phase measurement functions. Offering both Absolute and Additive(residual) measurement capabilities in one unit at no additional cost, the 7000 series is the most flexible solution on the market. The instrument comprises a two-channel, cross-correlation system with two internal, tunable references sources that also allows measurements with externally sourced references. We offer three platform options for the 7000 Series Phase Noise Testers: the 7070 1 MHz to 7 GHz, the 7300 1 MHz to 26 GHz, 7340 1 MHz to 40 GHz, 7350 1 MHz to 50 GHz, and the 7360 1 MHz to 65 GHz.

Two Channel Phase and Amplitude Noise Analyzer
DCNTS -190
-
The DCNTS is a two channel Phase and Amplitude noise analyzer. Its dual demodulator architecture allows the system to use cross-correlation to cancel its internal noise and limitation; it is like comparing the outputs of 2 systems and only display the similarities while rejecting differences. Its main extension is the Residual Noise measurement front-end which includes all necessary hardware to automatically measure residual noise on 2-ports devices either in RF frequencies or microwave. It could be a frequency multiplier or divider, an amplifier or any other phase coherent input to output device.

Voltage Controlled Phase Shifters To 3200 MHz
-
Pulsar's Voltage Controlled Phase shifters utilize a DC voltage to control the phase of the RF signal applied. These phase shifters utilize varactor diodes to produce the necessary phase requirements. Phase of the 180 and 360 degree designs are available, and phase can be controlled with a DC voltage 0-20 Vdc. Modulation of these phase shifters is typically 100 kHz, and maximum input power is +5 dBm.A wide variety of package styles are available, such as plug-in, flatpack, TO-cans, and connectorized housings, though the most popular are the miniature surface mount packages. Surface mount packages are available on tape and reel, for automated assembly techniques.

Three Phase Site Energy Meter Test Instrument Type KP-P3001-A
-
Bofa Instrument & Equipment Co., Ltd
Three-phase site energy meter test instrument type KP-P3001-A (without voltage and current source) is an ideal instrument to test all kind three-phase energy meters accuracy below 0.2, especially for meters on site. When we want test a meter errors, the tested meter must be on load condition (or we can say the tested meter must be working). The instrument can test the errors, by comparing energy impulse from the tested meter with energy impulse from the reference meter which inside the instrument. The equipment is box structure and weight is very light, easy to carry, it is very convenience to test the installed meters on site.
