Anritsu MT8801C - Notes on Fetching the Waveform Data

Section 8 Waveform Data Storage Format

8.1 Notes on Fetching the Waveform Data
(1) Fetching screen
• The waveform data to be fetched must be displayed on the MT8801C screen.
• Check that the measurement terminates before fetching the waveform data. If
Continuous measurement mode is set or measurement does not terminate, the
correct data cannot be fetched.
Examples of checking measurement termination:
(a) In Continuous measurement mode
1. Switch to Single measurement mode.
2. Read the End Event Status Register (ESR2) and check that the measure-
ment terminates.
(b) In Average measurement mode
• Read the End Event Status Register (ESR2) and check that both averag-
ing and measurement terminate.
(c) In Single measurement mode
• Read the End Event Status Register (ESR2) and check that the measure-
ment terminates.
(2) Response data
• When fetching two or more data items together, commas (,) are output as data
separators.
• The query command format is designed so that it can fetch all data items to-
gether. However, the number of data items actually fetched depends on re-
strictions placed on the external controller.
