Standard Directional Gyroscopes
4000B-series
-
The 4000B is our standard air-driven directional gyro. As the aircraft turns left or right, gears on the sensing unit and dial shaft translate this rotation into rotation of the instrument’s vertical dial. Left turns produce clockwise dial rotation and right turns produce counter-clockwise rotation. The gyro is controlled by a heading selector knob located on the lower left of the instrument. Pressing and turning the knob first disengages the dial shaft and then resets the dial to a new heading, which results in a new course indication. Releasing the selector knob re-engages the dial shaft. The on-course position of the pointer is always at the top of the azimuth circle (0° on the dial with the aircraft headed north).

2-18GHz Instantaneous Frequency Measurement Unit
DR073
-
Teledyne Defence & Space’s Instantaneous Frequency Measurement (IFM) module, also known as a Digital Frequency Discriminator (DFD), offers high speed frequency measurement across the full operating bandwidth.The IFM measures the frequency of RF signal present at its input and presents a result at its output as digital data. The RF input signal is conditioned by an RF amplifier that provides sufficient drive for the frequency resolving circuits. The raw video from the resolvers is digitised and processed into the required output format. There is additional timing and control circuitry which initiates the measurement process and provides handshake data to the host system processor.

Oil Immersed Transfer Standard
esi SR1030 Series
-
The esi SR1030 transfer standards consist of 12 equal steps. These steps are available in increments of 1 (SR1030-1), 10 (SR1030-10), 100 (SR1030-100), 1k (SR1030-1k), 10k (SR1030-10k) and 100k (SR1030-100k). The esi SR1030 provides four-terminal connections for each step or for series and parallel combinations of these resistance steps using the optional Series-Parallel (SPC102), Parallel Compensation Networks (PC101) and shorting bars (SB103). This improves power dissipation, stability and errors due to variance in temperature. The esi SR1010 and esi SR1030 are used for the same applications and are alike in configuration. The esi SR1030 differs from the esi SR1010 in that it is specially sealed, and values below 100 k are filled with oil to improve changes due to thermal variations.

Portable Three-Phase Energy Standard
PEWM-3C
-
The three-phase energy standard PEWM-3C is used for quick on-site tests of all types of electricity meters – for active, reactive or apparent energy, two-, three- or four-wire connection. Three voltages and three currents are measured at the same time. The current can be measured either via direct connection up to 10A (class 0.1), or with three current clamps (CC) to 120A, 150A or 1000A (class 0.2).

IEC Standard Burden Sets (Current)
IEC Burden Sets
-
Testing and calibrating current transformers often requires standard burdens of reliable accuracy and stability, and burdens that are immune to stray fields and harmonics. These burden sets have been carefully designed to meet these requirements. They also provide the standard burdens required for the testing of current transformers for metering service, and for the testing (within the current rating provided by the sets) of current transformers for relaying applications, all as called for by IEC (International Electrotechnical Commission) Publication 185: 1987.

Radio Frequency Scoring Tool
RFST
-
The Radio Frequency (RF) Scoring Tool (RFST) takes the guess work out of RF environment simulation. During RF environment simulation, the RFST provides clear persistent scoring and recording of the RF simulator’s performance. The RFST digitizes all RF signals in the form of digital Pulse Descriptor Words (PDWs) and associated In-phase/Quadrature (I-Q) data. This massive data stream is recorded for later (Post-Scenario) Analysis. Additionally, the RFST provides a real-time visual display of the accuracy of the RF output, easily visible through straight forward real-time indicators. The post analysis tool set allows an unlimited number of users to simultaneously assess previous RF simulator performance with compelling visual representations. The RFST is a perfect complement to our A2PATS product line offering everything you need for comprehensive environment simulation and analysis.
