E6651A Specifications
Signal analyzer specifications
Signal generator specifications
The test set will meet its warranted performance after one hour within the stated environmental
operating range plus one hour after turn on. Unless otherwise stated all specifications are valid over
the operating temperature range. Supplemental characteristics are intended to provide additional
information, useful in applying the instrument by giving typical (expected), but not warranted,
performance parameters at room temperature (20 to 30 °C). These characteristics are shown in
italics or labeled as nominal.
