BURST ADC1&2
A burst of conversions at exactly 56 µs/point (approximately 18 kHz) is
performed on both ADC1 and ADC2, either on receipt of the TADC3 computer
command or when the Trigger Burst Mode key is pressed. The results are stored
to the curve buffer, with the number of conversions being set by the curve length
control on the Curve Buffer menu - see section 5.3.22.
BURST ADC1 (VT)
This is the same as the BURST ADC1 mode, except that the sampling rate may
be set using the Time/Point control and that the computer command to initiate
acquisition is TADC4.
BURST ADC1 & 2 (VT)
This is the same as the BURST ADC1 & 2 mode, except that the sampling rate
may be set using the Time/Point control and that the computer command to
initiate acquisition is TADC5.
BURST ADC1 (RP)
This is the same as the BURST ADC1 mode, except that acquisition is initiated
on receipt of a rising edge at the TTL TRIG connector on the rear panel.
BURST ADC1 & 2 (RP)
This is the same as the BURST ADC1 & 2 mode, except that acquisition is
initiated on receipt of a rising edge at the TTL TRIG connector on the rear panel.
BURST ADC1 (RP VT)
This is the same as the BURST ADC1 (T) mode, except that acquisition is
initiated on receipt of a rising edge at the TTL TRIG connector on the rear panel.
BURST ADC1 & 2 (RP VT)
This is the same as the BURST ADC1 & 2 (T) mode, except that acquisition is
initiated on receipt of a rising edge at the TTL TRIG connector on the rear panel.
NOTE: When any of the burst acquisition modes are selected, the instrument
automatically changes the curves selected for storage, as shown on the Curve
Select menu (section 5.3.23), to be either ADC1 or ADC1 and ADC2.
TRIGGER BURST MODE
When one of the triggered burst modes is selected, this control is active and is shown
in bright text. Press the key adjacent to it to trigger data acquisition.
TIME/POINT
When one of the timed burst modes is selected, the time per point control is active
and is shown in bright text. This can be set to any value between 25 µs (ADC1 only)
or 56 µs (ADC1 and 2) and 5 ms in 1 µs increments.
Pressing the Previous Menu key returns control to Main Menu 2.
