Used WILLTEK 4291 #144751 for sale

WILLTEK 4291 is an RF and microwave test equipment with L-band capability that enables users to precisely measure radio frequency signals. The device has two measurement ranges, one for signals in the frequency range from 9 kHz to 1.8 GHz and another for signals between 2 to 8 GHz. The device has a frequency accuracy of 10 kHz and the measuring principle followed is the heterodyne technique using a micro-power signal source and correction algorithms. The power behavior is calculated using a synchronous detector and it has linearity up to 4 GHz. 4291 contains many features that make it an ideal solution for laboratory and field RF measurements: a wide frequency selection (-9kHz, 100 KHz-1.8 GHz, 2-8GHz); a wide power range (-7.5 dBm to +20dBm, -90dBm to +30dBm), and an independent power source. The power accuracy is within 1dB and the phase accuracy within 1 degree. WILLTEK 4291 also has a typical sweep speed of 200 mS/dB, two logarithmic sweeps available (20 dB, 60dB) and resolution bandwidth of 1Hz - 3MHz. Furthermore, the device has a variety of measuring functions such as withstanding voltage levels, return loss, antenna gain, and phase balance tests. 4291 is equipped with a standard DVM (DC Voltmeter) type measurement capabilities. This means that it can measure volts and current as well as monitor changes in phase or frequency of signals. These measurements can be used to calibrate the system, identify problems, and even pinpoint interference sources. WILLTEK 4291 has a parallel port, which can be used to connect to an external PC, a serial port to allow modem connection, an Ethernet port to allow network connection, and a USB port to facilitate connection to external devices, such as printers. Finally, 4291 has a self-test program to monitor health status. The program also allows the user to test the accuracy of the device and its system. In summary, WILLTEK 4291 is a versatile, reliable, and accurate RF test equipment that is ideally suited for laboratory and field testing. With its wide frequency range, power range, and variety of measuring functions, 4291 is the perfect tool for RF engineers, professional technicians, and hobbyists alike.
