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.
Start / Stop 10 kHz 100 kHz 1 MHz
0.1 Hz 750 900 1050
1 Hz 600 750 900
10 Hz 450 600 750
100 Hz 300 450 600
1 kHz 150 300 450

Start / Stop 10 kHz 100 kHz 1 MHz 50 MHz
0.1 Hz 1250 1500 1750 2150
1 Hz 1000 1250 1500 1900
10 Hz 750 1000 1250 1650
100 Hz 500 750 1000 1400
1 kHz 250 500 750 1150

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.
