The E8257D-540 PSG analog signal generator covers a specified range of 250 kHz to 40 GHz, with tunable operation from 100 kHz to 40 GHz. This extended millimeter-wave capability makes it well suited for characterizing wideband components, satellite communication subsystems, and high-frequency radar modules with 0.001 Hz frequency resolution.
The standard E8257D-540 delivers +15 dBm specified output from 0.4 to 3.2 GHz with up to +23 dBm typical. From 3.2 to 10 GHz, specified power remains +15 dBm with +22 to +23 dBm typical. At millimeter-wave frequencies from 20 to 40 GHz, specified output is +5 dBm with typical performance of +14 to +16 dBm.
At a 20 GHz carrier, the standard E8257D-540 achieves -37 dBc/Hz specified (-43 dBc/Hz typical) at 10 Hz offset and -114 dBc/Hz specified (-121 dBc/Hz typical) at 10 kHz offset. At 40 GHz, phase noise is -31 dBc/Hz specified at 10 Hz offset and -108 dBc/Hz specified at 10 kHz offset.
Yes, the E8257D-540 provides CW switching speed of less than 11 ms typical to within 0.1 ppm of final frequency above 250 MHz, with nominal performance under 7 ms. In step sweep mode, frequency switching is less than 9 ms typical and amplitude switching is less than 5 ms typical, supporting efficient automated test routines.
The E8257D-540 produces no sub-harmonics from 250 kHz to 10 GHz. From 10 to 20 GHz, sub-harmonics are less than -60 dBc, and above 20 GHz to 40 GHz they remain below -50 dBc. These specifications apply at +10 dBm or maximum specified output power, whichever is lower.
Yes, with Option 007, the E8257D-540 supports analog ramp sweep with maximum rates up to 400 MHz/ms above 3.2 GHz. Sweep time is settable from 10 ms to 200 seconds. It is compatible with the Keysight 8757D scalar network analyzer and supports two-tone master/slave operation where two PSGs synchronously track each other.
The E8257D-540 maintains level accuracy of plus or minus 1.0 dB from 0.5 to 20 GHz over the 15 to 35 degrees C temperature range with ALC on. Power level resolution is 0.01 dB, and temperature stability is 0.02 dB per degree C typical. Specifications apply in CW and list/step sweep modes.
Yes, with Option 1E1 step attenuator, the E8257D-540 can generate signals as low as -135 dBm, enabling sensitive receiver testing and bit error rate measurements. The attenuator provides 115 dB of range with fine adjustment via ALC, and the output power resolution of 0.01 dB ensures precise control at any level.
