Rear Panel Connectors
GPIB
Controls: The Agilent 53310A provides full programmability. All instrument settings and operating modes, except specific self-test routines, may
be remotely programmed via GPIB (IEEE Std
488.1-1987). The programming codes and formats
comply with IEEE Standard Codes, Formats,
Protocols, and Common Commands (IEEE Std
488.2-1987), and Standard Commands for
Programmable Instruments (SCPI) Standard,
Version 1990.0.
* “Final value” is defined as oscillator frequency 24 hours after turn-on.
** “Turn-off”,“turn-on”, and “off-time” apply to periods when power is disconnected
from the 53310A rear panel.
Data Acquisition and Transfer Rate: A 450 point
data record can be acquired and transferred to a
computer at a rate ~17 times per second, as tested
with an HP 9000, Series 300 controller. For this
