The Tektronix 1L30 is a 10.5 GHz spectrum analyzer plug-in module that transforms compatible Tektronix 500-series oscilloscopes into RF signal analyzers. Originally developed by Pentrix as the L-30 before Tektronix’s 1964 acquisition, this plug-in extends oscilloscope capabilities to cover microwave frequencies with calibrated sensitivity and frequency accuracy suitable for RF characterization and troubleshooting.
Technical Specifications
• Frequency Range: 925 MHz to 10.5 GHz
• Sensitivity: −105 to −75 dBm
• IF Center Frequency: 150 to 250 MHz passband
• Frequency Dispersion: 0.2 to 10 MHz/cm (1-2-5 sequence); 1 to 500 kHz/cm
• Display Linearity: ±3% over 10 cm
• Dial Accuracy: ±(2 MHz + 1% of dial reading) with IF CENTER FREQ control at 000, FINE, RF, and IF CENTER FREQ controls centered
• Warm-up Time: 20 minutes
• Operating Temperature: 0°C to 50°C (after 4-hour thermal stabilization)
– Key Features
• Derives all power from the host oscilloscope; no external power supply required for standard operation
• Optional external power capability using Tektronix Type 127 or Type 132 power supplies with 100-volt sawtooth signal
• Plug-in form factor enables direct integration without additional cabling or external modules
– Compatibility & Integration
The 1L30 is compatible with Tektronix 530-, 540-, 550-, and 580-Series oscilloscopes. A Type 81 Plug-In Adapter is required for 580-Series integration. The module was produced from 1965 to 1971.
