When sweeping the frequency of a signal applied to the DUT (F), there is a

frequency difference between the input side and output side of the DUT

due to the delay time that occurs in the DUT (Delta T). This frequency

difference (Delta F) becomes larger as the electrical delay time of the DUT

becomes longer and the frequency sweep speed becomes faster, as shown

in the following equation.

When measuring a DUT with long electrical delay time, if you perform

measurement (sampling) while sweeping the measurement signal as in the

swept mode, a measurement error occurs due to the difference between

the frequency outputted from the source port and the frequency actually

measured at the receiver port.

Therefore, when measuring a DUT with a long electrical delay time,

generally use the stepped mode to prevent the measurement error

described above. However, if you need to shorten the sweep time,

evaluate the measurement error as described below to determine the

sweep mode that should be used.

Turning off the updating of information displayed on the LCD screen

eliminates the processing time required to update displays within the

analyzer, improving measurement throughput. If it is not necessary to

check displayed information during measurements, turning off real-time

updating is an effective means of improving throughput.

The updating of information displayed on the LCD screen can be switched

using the following procedure:

2. Click Update to switch the updating of displayed information on the

LCD screen on/off.

When the LCD screen update is turned off, Update Off appears on

Instrument Status Bar.

The E5071C executes Port Characteristics Correction in the data processing

flow shown in Data Processing Flowchart, by using the system calibration

data set at the factory. This system error correction process is not required

if the user performs proper calibration by using the

softkeys that subsequently appear, which automatically turns on error
