Agilent / HP / Keysight 8341B
8341B Synthesized Sweeper, 10 MHz to 20 GHz
The Agilent/HP 8341B synthesized sweepers deliver the combined high performance of a synthesizer and a broadband sweep oscillator in one instrument that is completely controllable via the HP-IB.
The efficient combination of performance and versatility is ideal for manual or automatic test systems and in many cases enables the 8341B to replace a sweep oscillator, a frequency counter, an RF synthesizer, and a microwave synthesizer.
The synthesized broadband frequency coverage and precise 1 to 4 Hz frequency resolution are generated by indirect synthesis techniques, enabling the 8341B to achieve the same low single sideband phase noise performance as the 8671B and 8673 series synthesized signal generators.
The Agilent 8341B feature CW switching times of better than 50 ms. Additionally, a “Fast Phase-lock” programming command can be used to reduce typical CW switching times to between 11 and 22 ms.
Option 003 on the 8341B delivers excellent harmonic performance at least 50 dB below a 1.4 to 20 GHz carrier. This low-harmonics option is particularly useful for demanding EW receiver testing, and scalar analysis of frequency selective devices such as filters.
The 8341B provides high output power which can be controlled down to -110 dBm with 0.05 dB resolution. High power resolution is complemented by outstanding accuracy with > 20 dB dynamic range for complete characterization of level-sensitive devices.
The Agilent 8341B have a high-performance pulse modulator 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 8341B also feature dc-coupled amplitude modulation with a 3 dB bandwidth of 100 KHz and a minimum depth of 90%, and frequency modulation with rates from 50 kHz to 10 MHz and peak deviations to 10 MHz. And with the 8341B, pulse, amplitude and frequency modulation can be used simultaneously.
Along sweep widths as narrow as 100 Hz or as broad as the full frequency range of the HP 8341B permit rapid and thorough testing of any device within their broad frequency ranges. To simplify swept measurements, five frequency markers are provided along with usual marker functions such as marker sweep, marker to center frequency and marker difference.
Besides being excellent stand-alone general purpose sources, the 8341B is also ideal source for precision microwave network analysis, where a significant part of measurement accuracy depends on the frequency accuracy, stability, signal purity and source/analyzer interface of the sweeper used.
