Leader LG 3226 Overview

The LG 3226 is a new, economy synthesized signal generator and fully programmable from 100 kHz to 2 GHz offering accuracy and stability needed to characterize designs. Frequency switching speed is <50 ms typical to the settled carrier frequency. SSB phase noise is specified to be -115 dBc/Hz to -130 dBc/Hz enabling work close in to the carrier. Simultaneous modulation capabilities include AM+FM, DC-FM + internal FM, FM internal + FM external (FM dual tone). Standard AM is (0 to 99.9%) and FM goes to 500 kHz peak deviation with carrier >1.04 GHz. FM modulation polarity can be selected. RF output is referred to dBm/dBm into 50W or dBm EMF. A dynamic range of -133.0 to +13.0 dBm allows testing of very sensitive receivers. A continuous variable output mode over a ±5 dB range optimizes precise hysteresis testing in squelch circuits. The offset function masks attenuation or gain of devices connected to the output and matches levels. Four output presets can be set for commonly used levels and a RF on/off key is provided. Step modes for output level as well as relative D frequency and RF frequency and D level modes clarify front panel operation when incrementing at odd frequencies or output levels. Memory capacity totaling 1,000 presets simplifies efficient high-speed throughput of repetitive complex test sequences. A panel lock mode prevents erroneous operation on production lines. Presets can be cloned with the data send/edit function one or ten groups at a time via the GPIB port. This extends test repeatability across multiple generators adding productivity All in all, the LG 3226 is up to many challenging requirements for R&D, production testing of communication applications for single side-band receivers, beepers, high frequency components, filters and local oscillators.
