Description of the Microwave Frequency
Counter/Power Meter/DVM
The Agilent 53147A, 53148A, and 53149A are capable of measuring
frequencies from 10 Hz to 125 MHz on Channel 1 and from 50 MHz to
20 GHz (53147A), 26.5 GHz (53148A), and 46 GHz (53149A) on Channel 2.
These instruments are also capable of measuring power (the power and
frequency ranges for power measurement are dependent on the power-
sensor model used) and DC voltages up to ±50 VDC. All three instruments
have a maximum frequency resolution of 1 Hz.
The Agilent 53147A, 53148A, and 53149A provide GPIB and RS-232 serial
interfaces and are suitable for field, bench-top, and ATE operation.
The basic measurement functions of the Agilent 53147A/148A/149A
include Frequency, Relative Frequency, Frequency Offset, and Power
(including Power Offset and Relative Power). All of these features are
accessible from the front panel and over the GPIB and RS-232 interfaces.
The Agilent 53147A/148A/149A includes the following additional
measurement functions and features that are designed specifically for
manufacturing and service applications:
• 1, 2, 5, and 10 MHz external reference capability
• Optional high-stability oven oscillator for high-accuracy needs and
lengthened calibration cycles
• Frequency and power offset capabilities for relative measurements
• SCPI programming capability
Battery and dc input option for operation in locations where ac
•
power is unavailable
• Optional soft carrying case for safe transportation and mobile use
Programmable control is performed via a GPIB or an RS-232 serial
interface. The GPIB and RS-232C ports are standard for the Agilent
53147A, 53148A, and 53149A.
