1000-P7

The General Radio was introduced in 1954 Catalog N and remained available through Catalog R 1963.

The Type 1000-P6 is an accessory am modulator for oscillator frequencies between 60 and 2500 MHz. It uses two 1N21B microwave diodes modulator which can be biased up to 4 V maximum, a 1.5 V battery or 0 to 4 V power supply is recommended.

Specifications

• Carrier Frequency Range: The useful carrier-frequency range is 60 to 2500 MHz
• Modulation-Frequency Range: 0 to 20 MHz. For pulsing, the rise-time contribution is less than 20 ns
• Impedance: source and load impedances are 50 Ω, The impedance at the modulation input is 50 ohms ±5%
• Bias: internal battery, adjustable 0 to 3 V (2 D-cells)
