Used WANDEL & GOLTERMANN K757 #9352502 for sale

WANDEL & GOLTERMANN K757 is an electronic test equipment for the analysis of high frequency devices. This device uses a frequency-controlled modulation technique to measure the magnitude and phase response of devices. It is suitable for testing ultra-high frequency (UHF) circuits, either in components or in integrated circuits. K757 employs a frequency-controlled modulation technique, with a primary signal at one frequency and a reference signal at a second frequency. The primary signal is applied to the device under test and the reference signal is used to measure the output of the device. The output is then compared to the reference signal, allowing the magnitude and phase of the device under test to be measured. WANDEL & GOLTERMANN K757 is capable of measuring frequency response from DC to 1GHz, making it useful for testing the high frequency components of radio frequency instruments. K757 also features a two-channel receiver chain, with a built-in amplifier and filter that can provide a wide range of gain and bandwidth adjustability. WANDEL & GOLTERMANN K757 supports both conventional and vector receivers. K757 has a built-in high resolution display that allows accurate comparison of the input and output signals from the device under test. This display can be used to judge the linearity of the device, as well as the level of distortion. WANDEL & GOLTERMANN K757 also features a test port for connecting external test probes or instruments, and a source port for evaluating modulation. K757 is an excellent choice for the testing of high frequency devices, as it offers a wide array of measurement capabilities and supports a range of input and output tests. It is well suited to both engineering and manufacturing environments, providing a reliable and versatile testing solution.
