Agilent M9168C PXI Programmable Step Attenuator Module
The M9168C PXI programmable module offers controlled attenuation for advanced RF systems. The unit comes with a compact PXI module supporting DC to 26.5 GHz operation. The attenuation resolution remains fixed at 1 dB step which supports accurate signal conditioning needs. The programmable module shows a repeatability rating of 0.03 dB which maintains stable long term calibration. Each internal section supports 5 million life cycles which strengthens durability under demanding repetitive operations. Insertion loss remains 2.5 dB from DC to 6 GHz which supports efficient low frequency performance.
The insertion loss increases to 4.0 dB across 6 GHz to 18 GHz which matches expected behavior. At higher ranges the value reaches 5.0 dB across 18 GHz to 26.5 GHz. Return loss remains 16 dB with VSWR 1.35 from DC to 6 GHz for stable matching. The M9168C programmable module reaches 7 dB with VSWR 2.61 from 18 GHz to 26.5 GHz which defines behavior. Maximum input power supports 1 W average and 50 W peak for short duration pulses. Maximum reverse power equals the same 1 W average and 50 W peak for protection needs. The switching speed of 20 ms enables predictable transitions when conducting controlled attenuation updates.
The RF connector uses a 3.5 mm female interface which remains SMA compatible across supported ranges. Operating random vibration meets 5 to 500 Hz at 0.3 g RMS which supports stable chassis integration. The M9168C programmable module contains handling shock that uses a half sine wave form at 120 in/s for short duration impacts. The transportation shock uses a trapezoidal profile at 50 g which protects internal sections under load. The operating altitude reaches 15,000 ft which equals 4600 m for consistent working across environmental ranges. The contact material uses beryllium copper with gold plating which ensures reliable conduction under repeated cycling. Warm-up time depends on the PXI chassis warm-up requirement which aligns module equilibrium conditions.
The Agilent M9168C PXI Programmable Step Attenuator Module integrates within PXI architectures that require controlled attenuation for dynamic multi-channel measurement systems. It provides predictable behavior during rapid test cycles. Signal paths maintain calibrated impedance along the full range which preserves measurement integrity under diverse loads.
