3.5 General Measurement Settings

3.5.1 Number of data points per trace

Per default, the number of points displayed in every trace is depending on the start and stop offset

frequency. Data for SERIES 7000 / SERIES 7000 and MODEL 7070 /MODEL 7300 are shown in

Table 1 and 2.

3.5.2 Measurement time (using GUI)

The measurement time required by the SERIES 7000 is depending on several parameters. The total

measurement time consists of a setup time, sampling time, and post-processing time.

3.5.2.1 The Setup Time

The setup time largely depends on the user settings and reference sources used. Very low noise

sources tend to have a small tuning sensitivity and behave slowly and with narrow loop bandwidths the

locking process takes increasingly more time.

The setup time depends on the user configuration and measurement frequency and consists mainly

on performing calibration steps and acquiring phase lock on the references sources.
