The Wiltron 660-C-8090-7 is a test set accessory engineered to extend network analyzer capabilities with enhanced measurement precision and signal control. This component integrates with Wiltron 6600A Series sweep generators and associated network analyzers to deliver leveled output power, multiple sweep modes, and precise frequency control across broad and narrow-band applications. Designed for research, development, and production environments requiring demanding RF measurement workflows.
Technical Specifications
Frequency Range:
The accessory supports operation from 10 MHz to 40 GHz depending on paired network analyzer configuration.
Output Power:
Leveled output power ranges from −110 dBm to +10 dBm across the supported frequency range. Power variation with temperature is ±0.08 dB/°C for internally leveled systems.
Leveling Modes:
• Internal Leveling — maintains output power at the front panel connector
• External Detector Leveling — levels at remote test positions using a directional detector
• Power Meter Leveling — enables leveling at remote test positions with a power meter
An Unleveled Indicator illuminates when output power cannot sustain leveling across the selected sweep range.
Modulation:
External AM input via rear panel BNC connector, 10 kΩ impedance, 1 dB/V sensitivity, DC–50 kHz frequency response.
Sweep Capabilities:
Supports broadband and narrow-band sweeps, two narrow-band symmetrical sweeps, and power sweep functionality with 15 dB variation range per sweep for active device characterization.
Markers:
Up to eight markers for identifying swept frequencies, AF sweep center frequencies, and CW or sweep limits.
Signal Purity:
• Harmonic content <60 dBc above 2 GHz
• Residual FM <10 kHz peak up to 20 GHz in CW or narrow-band mode
• CW frequency accuracy ±10 MHz over 10 MHz–20 GHz; external phase-locking achieves ±10 Hz or better
– Key Features
• Multi-mode leveling for flexible test configurations
• Low harmonic distortion via fundamental oscillators
• Extended frequency marker capability for precision measurements
• Power sweep for gain and power device testing
– Typical Applications
Component characterization, active device gain measurement, RF system validation, and production test support across microwave frequencies.
– Compatibility & Integration
Designed for integration with Wiltron 6600A Series sweep generators and network analyzers requiring external leveling, modulation, and sweep control.
