100 kHz to 26.5 GHz High-Power Signal Generator APSIN26G-TP

The APSIN26G-TP is a high output power, low phase noise, fast-switching microwave signal generator covering a frequency range from 100 kHz up to 26.5 GHz. The APSIN26G-TP provides leading edge output power up to +25 dBm along with a complementary range of features at a excellent price/performance ratio. It is targeted for applications where a high-quality, high output power CW microwave source with analog modulation is required. The APSIN26G-TP includes amplitude modulation, frequency chirps, and fast pulse (train) modulation as standard. The APSIN26G-TP operates with an ultra-stable temperature compensated 100 MHz reference (OCXO) and can be phase-locked to any external reference from 1 to 250 MHz. This instrument offers a reliable and powerful alternative to expensive high-end microwave signal generators, where compact size, high output power, and excellent microwave performance at an attractive cost is required.
