  • Patent number: 10261111
    Abstract: An oscilloscope includes a probe and an analog to digital converter. The probe detects a varying electronic signal and produces an analog signal. The analog to digital converter converts the analog signal to a digital signal. The oscilloscope detects vertical movement of the digital signal as a first digital trigger triggered at a trigger time. A segment of the digital signal is compared with predetermined parameters for the varying electronic signal received from a user to confirm whether a pattern of the varying electronic signal in the segment matches the predetermined parameters. When the pattern of the varying electronic signal in the segment matches the predetermined parameters, the process includes generating a display showing the varying electronic signal in the segment based on the trigger time.

  • Patent number: 10230384
    Abstract: A receiver includes a variable resolution analog-to-digital converter (ADC) and variable resolution processing logic/circuitry. The processing logic may use feed-forward equalization (FFE) techniques to process the outputs from the ADC. When receiving data from a channel having low attenuation, distortion, and/or noise, the ADC and processing logic may be configured to sample and process the received signal using fewer bits, and therefore less logic, than when configured to receiving data from a channel having a higher attenuation, distortion, and/or noise. Thus, the number of (valid) bits output by the ADC, and subsequently processed (e.g., for FFE equalization) can be reduced when a receiver of this type is coupled to a low loss channel. These reductions can reduce power consumption when compared to operating the receiver using the full (i.e., maximum) number of bits the ADC and processing logic is capable of processing.

    Abstract: A continuous-time sigma delta modulator circuit includes a scaling circuit that scales an input analog signal by a selectable range of different scaling factors in order to change a range of signal levels of the input analog signal to a desired range of signal levels in a scaled analog signal prior to conversion of the scaled analog signal to a digital signal. The scaling factor is selected based on the range of signal levels of the input analog signal in order to provide signal levels of the scaled signal within a desired range. The scaling circuit maintains current flow of the input analog signal at a substantially constant level regardless of the different scaling factors that are used to scale the input analog signal.

In the radio field intensity measurement device, a battery is provided as a power source for power supply and the battery is charged by a received radiowave. When a potential of a signal obtained from the received radiowave is higher than an output potential of the battery, the power is stored in the battery. On the other hand, when the potential of the signal obtained from the received radiowave is lower than the output potential of the battery, power produced by the battery is used as power to drive the radio field intensity measurement device. As an element to display the radio field intensity, a thermochromic element or an electrochromic element is used.

  • Patent number: 9121870
    Abstract: Clamp meter with detachable clamp and a clamp storage area. The clamp meter includes a clamp and a housing. The clamp includes a measurement end and a handle portion. The measurement end includes a first measurement portion and a second measurement portion. The handle portion includes a first handle and a second handle. The housing includes a recess configured to removably receive the clamp when the clamp is not in use. The housing is connected to the clamp via a cord. When the clamp is received in the recess, the first measurement portion and the second measurement portion are positioned completely within the recess, the first handle and the second handle extend at least partially from the recess, and the recess prevents the clamp from being used. The clamp is capable of being removed from the recess in a one-handed use position.

  • Patent number: 9121877
    Abstract: A system for measuring phase attributes of high voltage electrical lines comprises first and second high voltage probes. Each of the probes comprises a sensing element for selectively measuring voltage of a high voltage electrical line, a processing device for detecting zero crossings of the measured voltage and applying a time tag to the zero crossings, and storing samples of the amplitude and time tagged zero crossings. A transceiver transmits storage samples. A user interface device is remote from the first and second high voltage probes and comprises a transceiver for receiving transmitted storage samples. A memory stores received samples of the time tagged zero crossings for the first and second high voltage electrical lines. A processor is operatively associated with the memory for determining phase relationships between the first and second high voltage electrical lines. A display displays the phase relationships.

  • Patent number: 8981759
    Abstract: A multimeter includes: a rotary switch which selects a measurement function; a common terminal hole into which a connector of a test probe is inserted; selection terminal holes into which the connector of the test probe is selectively inserted; and shutter plates which selectively open the selection terminal holes. The rotary switch includes convex portions. The shutter plate includes a hole corresponding to the common terminal hole so that the shutter plate rotates by using the center of the common terminal hole as the rotation axis and includes a concave portion engageable with the convex portion so that the shutter plate rotates to open the selection terminal holes by the movement of the convex portion. The shutter plate includes a concave portion engageable with the convex portion so that the shutter plate opens and closes the selection terminal hole by the movement of the convex portion.
