  • Publication number: 20210148951
    Abstract: An accessory device has a test port, an instrument port to connect to an instrument having an operating bandwidth, and one or more configurable signal paths connectable between the test port and the instrument port to convert a signal from the test port having a first frequency range to a signal having a second frequency range different than the first frequency range. A test and measurement system has a test and measurement instrument having an operating bandwidth, and an accessory device. The accessory device has a first instrument port to connect the accessory device to the test and measurement instrument, a test port to connect the accessory device to a device under test, and one or more configurable signal paths connectable between the test port and the instrument port to down-convert a signal from the test port having a first frequency range to a signal having a second frequency range lower than the first frequency range.

  • Publication number: 20200386801
    Abstract: A test and measurement device measures an insertion loss of a material under test. The test and measurement device includes a reference device in contact with a first surface of a material under test, the reference device including a reflective component and an absorbing component. A testing device is in contact with a second surface of the material under test, opposite the first surface. The testing device includes a first transmitter to output a first signal at a predetermined frequency to the reflective component of the reference device through the material under test, a first receiver to receive a first reflected signal from the reflective component, a second transmitter output a second signal at the predetermined frequency to the absorbing component of the reference device through the material under test, and a second receiver to receive a second reflected signal from the material under test.
