Used AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 43521A #9213105 for sale

AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 43521A is a general purpose signal generator. It is used to generate accurate signals for oscilloscope measurements, circuit testing, broadcast testing, and other electronic measurements. HP 43521A is a versatile instrument, with features such as frequency, phase, and amplitude modulation. It also offers pulse widths of up to 30kHz, with a total sweep range up to 110MHz with extremely low distortion. In addition, it has excellent phase noise with only -105 dBc/Hz at 10 kHz offset. The device utilizes dual-comb mode, which allows two independent signals to be generated simultaneously, and has an adjacent channel selectivity of 40 dB at 1 MHz. This feature is useful for testing multiple frequency devices, such as RF filters. The 44521A also features an internal arbitrary waveform generator, which is suitable for more sophisticated tasks. AGILENT 43521A is built around a TFT touch screen, allowing the user to easily navigate and adjust the many settings available. Primarily, the signal generator can produce pure sine waves, but also rectangular, triangle, sawtooth, white noise, and stepped waveforms. The display includes an oscilloscope-style XY graph, so the user can see the output in a graphical format. The device is powered by a regulated switching power supply which can provide up to 50 watts of RF power. This helps minimize the size of the device, but still allows sufficient power for most measurements. It also includes an integrated frequency counter to monitor any signals sent to the device, as well as active noise cancelation, which helps to reduce any interference from outside sources. HEWLETT-PACKARD 43521A can be tailored to the user's specific needs using a variety of optional accessories. These accessories include external power amplifiers, switchers, connectors, and filters, in addition to a range of probes and adaptors for connecting to various patterns. The 44521A also offers digital I/O for external control, enabling remote control capabilities. Overall, KEYSIGHT 43521A is an extremely versatile signal generator with great features such as dual-comb mode and built-in waveform generator. It provides great performance and accuracy, and its comprehensive array of accessories make it highly suitable for all kinds of measurements.
