The HP 8341B Synthesized Sweeper delivers the combined high-performance of a synthesizer and a broadband sweep oscillator in one instrument that is completely controllable via the Hewlett Packard Interface Bus (HP-IB). This efficient combination of performance and versatility is ideal for manual or automatic test systems and enables the HP 8341B to replace a sweep oscillator, a frequency counter, an RF synthesizer, and a microwave synthesizer. The synthesized broadband frequency coverage and the precise 1 to 4 Hz frequency resolution (depending on frequency band) are generated by indirect synthesis techniques. The HP 8341B features CW switching times of better than 50 ms (typically <35 ms). Additionally, a Fast Phase-lock programming command can be used to reduce typical CW switching times to between 11 and 22 ms (depending on frequency step size and absolute frequency value). The HP 8341B provides high output power which can be varied all the way down to the minimum level (-110 dBm) with 0.05 dB resolution and feature power sweep capability with >20 dB dynamic range for complete characterization of level-sensitive devices. The HP 8341B has high-performance pulse modulators with ON/OFF ratio >80 dB and rise and fall times <25 ns. Pulse amplitude is leveled and can be as narrow as 100 ns. The HP 8341B also features dc-coupled amplitude modulation with a 3 dB bandwidth of 100 kHz and a minimum depth of 90%. Pulse and amplitude modulation can be used simultaneously. It also offers frequency modulation capability, with modulation rates from 50 kHz to 10 MHz and peak deviations to 10 MHz. Specifications. Frequency Range: 10 MHz to 20.0 GHz. Resolution (CW Mode): 1 Hz, 0.01 to <7.0 GHz; 2 Hz, 7.0 to <13.5 GHz; 3 Hz, 13.5 to 20.0 GHz. Harmonics (up to 20.0 GHz) of output frequency: <-35 dBc. RF Output Range: -110 dBm to +20 dBm.
