Modifiers: Modifiers Used Only With TØ Mode
Modifier Description: This modifier places the instrument in max hold mode.
Every time the analyzer is talk-addressed, the instru-
ment will output the maximum reading seen since the
mode was activated.
Modifier name: MAXH
Modifier syntax: MAXH hs state
State definition: ON, +, OFF, -
Modifier Description: This modifier places the instrument in min hold mode.
Every time the analyzer is talk-addressed, the instru-
ment will output the minimum power reading seen since
the mode was activated.
Modifier name: MINH
Modifier syntax: MINH hs state
State definition: ON, +, OFF, -
Modifier Description: This modifier places the measurement in relative
reading mode. When the command is received by the
analyzer, it takes the current power reading and stores it
as a reference. Every time the analyzer is talk-
addressed, the instrument will output the difference
between the current reading and the stored reference
reading (in dB).
Modifier name: REL
Modifier syntax: REL hs state
State definition: ON, +, OFF, -
Modifier Description: SRQ in TØ mode operates slightly differently than SRQ
in T2 mode. In the TØ mode, when the SRQ modifier is
sent the analyzer will wait until the number of averages
defined for the channel has been completed. The
analyzer will then set the event complete bit in the
external status register. The service request and
external status bits are set in the instrument status byte.
The SRQ interrupt line on the GPIB bus is asserted.
This should cause an interrupt in the external controller
which may be handled by an interrupt service routine.
Modifier name: SRQ
Modifiers: Modifiers Used Only With T1 Mode:
NONE: There are no modifiers specific to the T1 mode.
