The HP/Agilent 70341A is a 1-slot Frequency Extension Module that expands the low-frequency capabilities of the HP/Agilent 70340A Modular Signal Generator. Operating as part of an MMS (Modular Measurement System) mainframe, the 70341A extends the 70340A’s native 1 GHz to 20 GHz range downward to 10 MHz, delivering unified frequency coverage from 10 MHz to 20 GHz through a single RF output connector.
## Technical Specifications
• **Frequency Range Extension:** 10 MHz to 20 GHz (combined with 70340A)
• **70340A Native Range:** 1 GHz to 20 GHz
• **70341A Extension:** Adds 10 MHz to 1 GHz coverage
• **Architecture:** Frequency divider design
• **Phase Noise Performance:** 6 dB per octave reduction
• **Broadband Noise:** Reduced compared to mixing techniques
• **Output:** Single RF connector
• **Level Accuracy and Flatness:** No degradation in combined system
## Key Features
• Frequency divider architecture minimizes phase noise and broadband noise
• Maintains signal integrity across the entire 10 MHz to 20 GHz spectrum
• Occupies single MMS slot for space-efficient integration
• Rear-panel connectivity to 70340A for seamless operation
• Compatible with SCPI and IEEE 488.2-1987 programming standards
• Optional CIIL programming support available
## Typical Applications
• Low-frequency signal generation and analysis (10 MHz and above)
• Extended-range RF testing and characterization
• Frequency-dependent measurements requiring phase noise control
• Multi-frequency test scenarios spanning decade ranges
## Compatibility & Integration
The 70341A integrates within an MMS mainframe alongside the 70340A (4-slot generator module). Installation places the 70341A immediately to the right of the 70340A with adjoining rear-panel connections. Typical MMS configurations include the HP 70001A mainframe, HP 70206A display module, HP 70340A signal generator, and HP 70341A frequency extension module. The module requires an MMS-compatible mainframe for operation.
