Fluke 6080A Generator
Manufacturer:
Fluke
Model: 6080A
Date: 1989
Category: Measurement instruments
Group: Generator
Description: SYNTHESIZED SIGNAL GENERATOR
Information:
                                    INTRODUCTION 1-1.
The 6080A/AN Synthesized RF Signal Generator (also referred
to as the "signal
generator") is a fully programmable, precision, synthesized
signal generator. The
6080A/AN is designed for applications that require good
modulation, frequency
accuracy, and output level performance with excellent
spectral purity. The signal
generator is well suited for testing a wide variety of RF
components and systems
including filters, amplifiers, mixers, and radios,
particularly off-channel radio testing.
Specifications of the 6080A/AN are provided at the end of
this section. The salient
features of the 6080A/AN are as follows:
• RF frequency range of 0.5 MHz to 1024 MHz in 1 Hz steps
• RF level range of +13 to -137 dBm in 0.1 dB steps
• Internal and External Modulation: AM, FM, and Pulse
• Internal 10 Hz to 100 kHz Synthesized Sine Wave Modulation
Oscillator
• Fifty Storable and Recallable Memory Locations
• Standard IEEE-488 (GPIB) Interface, complying with
ANSI/IEEE Standards
488.1-1987 and 488.2-1987
• Closed-case calibration capabilities for Frequency
Reference, AM, FM, and
Level.
