{RECTangular|HAMming|HANning|BLAckmanh arris|KAIser|FLATtop}
RF:WINdow?
Arguments
RECTangular — window function equivalent to multiplying all gate data by one
(sometimes known as a Dirichlet window).
HAMming — a high or moderate resolution window based on a cosine series.
HANning — a high or moderate resolution window based on a cosine series.
BLAckmanharris — a low-resolution (high dynamic range) window based on a
cosine series.
KAIser — a high or moderate resolution window.
FLATtop — a low-resolution (high dynamic range) window.
Examples
RF
:WINdow BLA
sets the window to BLAckmanharris.
RF:WINDOW? KAISER indicates that the window function is set to the default,
K
aiser.
ROSc:SOUrce
This command specifies the source for the time base reference oscillator. The
reference oscillator locks to this source. Depending on the command argument
that you specify, you can use an external reference or use the internal crystal
oscillator as the time base reference.
This command is also useful for synchronizing multiple instruments.
NOTE. If using a n external oscillator, its input frequency variation tolerance
needs to be 10MHz +- 1% (ie. 9.9 MHz to 10.1MHz) and 7Vp-p maximum voltage.
Conditions
Available for 4000 series models only. For MDO3000, this query always returns
UNLOCKED.
