pattern extinction rate dB.
You can set the level within �10 divisions. The unit changes depending on the set
conditions.

function, see section 7.7.

Notes about the Telecom Test
• When you execute a telecom test, all waveforms other than the source waveform are
displayed as follows:
• W
aveforms are not displayed if the display interpolation is turned OFF (see section
8.3 for details).
• W
aveforms are displayed at low intensity if the display interpo
lation is not OFF.
• You cannot execute a mask test, if GO/NOGO or history searc
h is in progress.
• When you turn the telecom test ON (open the setup menu), accumulation will turn ON.
The accumulation mode is set to Count.
Note
Because the sample point count is calculated using interpolated data, the value returned for it
may not correspond to the record length.
