HORizontal:FASTframe:LENgth
Description
This command sets or queries the horizontal record length to the num-
ber of sample points in each frame. This command is equivalent to se-
lecting FastFrame Setup from the Horiz/Acq menu and entering a value
in the Rec Length box. FastFrame captures a series of triggered acquisi-
tions with minimal intervening time between them.

Syntax 1
HORizontal:FASTframe:LENgth <NR1>
Syntax 2
HORizontal:FASTframe:LENgth?
Argument
H <NR1>
<NR1> represents the supported value for horizontal record length in
Fast Frame mode. In addition, to the allowable record length in nor-
mal (single frame) mode, 50 and 250 point record lengths are per-
mitted in Fast Frame mode.
For instruments with standard memory configuration, you can have a
maximum Fast Frame record length of 8M, 4M, or 2M for 1, 2, or 4
channel operation, respectively. For instruments with 3M memory
option, the maximum Fast Frame record lengths are 16M, 8M, or 4M
for 1, 2, or 4 channel operation, respectively
For more information about valid data point ranges, select Specifica-
tions from the Help menu; then select the Horizontal & Acquisition
tab.
Example 1
HORIZONTAL:FASTFRAME:LENGTH 5000
This command sets the horizontal record length to 5000 sample points
in each frame.
Example 2
HORIZONTAL:FASTFRAME:LENGTH?
This query might return
:HORIZONTAL:FASTFRAME:LENGTH 25000
This indicates that the FastFrame record length is set to 25000 sample
points in each frame.
