50 CONT SWITCHING MAYDAMAGE MECH SW
RF output power switch, input attenuator switch at input R/A/B, or internal mechanical switch
in the S-parameter test set is switching sweep by sweep, because RF power level or the input
attenuator setting is dierent between two channels and the dual channel is turn on, or
continuous trigger mode is selected after full 2-port calibration is performed when HP 4395A
is used with the S-parameter test set. To avoid premature wearing out of the output power
switch, input attenuator switch, or internal switch of the S-parameter test set, change trigger
type to HOLD, SINGLE, or NUMBER of GROUP to hold sweep after measurement required. Or,
for example, turn o the dual channel, or set the power level and the input attenuator of both
channels to the same setting.
135 COUPLED CHAN - BETWEEN NA&NA OR ZA&ZA
The analyzer types of both channels must be the network analyzer mode or impedance
analyzer mode when the coupled channel is turned on. It is not possible to turn the coupled
channel on in spectrum analyzer mode.
74 CURRENT EDITING SEGMENT SCRATCHED
The current editing segment for the list table and the limit line is scratched when the following
cases occur ( HP-IB only ):
When EDITLIST (edit list table) command is received while editing a segment for the list
table.
When EDITLIML (edit limit line) command is received while editing a segment for the limit
line.
Send LIMSDON (limit segment done) or SDON (segment done) to terminate editing segment.
16 CURRENT PARAMETER NOT IN CAL SET
HP-IB only. Correction is not valid for the selected measurement parameter
.
D
0 230 Data corrupt or stale
Possibly invalid data. New reading started but not completed since last access.
0 225 Data out of memory
The analyzer has insucient memory to perform the requested operation.
0 222 Data out of range
A legal program data element was parsed but could not be executed because the interpreted
value was outside the legal range as dened by the analyzer (see IEEE 488.2, 11.5.1.1.5).
0 231 Data questionable
Indicates that measurement accuracy is suspect.
0 104 Data type error
The parser recognized an unallowed data element. For example, numeric or string data was
expected but block data was encountered.
