Error number: 79
79 Not available for this format
Selected measurement parameter or display format could not be executed. For example,
during the Dielectric Measurement Mode or in Magnetic Substance Measurement Mode,
DISP:TRAC{1-5}:GRAT:FORM command on page 357 has been used in order to set
into unchangeable display format (Smith Chart or Admittance Chart).
Select the measurement parameter or display format which are possible to be selected.
80 Not available for this fixture
An invalid command has been sent toward presently selected text fixture. For example,
during when the 16197A is selected,
CALC{1-5}:FORM command on page 298 has been
used in order to set into unchangeable measurement parameter (Complex dielectric
constant against the complex trace).
Select the measurement parameter or display format which are possible to be selected.
90 No marker delta - parameter not set
Reference marker’s gpcdeltauppergpc mode is in Off and CALC{1-5}:MARK:SET
command on page 336 or CALC{1-5}:MARK:FUNC:DOM:SPAN command on
page 319 have been used in order to set the gpcdeltauppergpc figures to span rate within
the sweep range or within the partial search range.
First, use CALC{1-5}:MARK:REF command on page 328 to display the reference
marker. Second, use CALC{1-5}:MARK:REF:TYPE command on page 333 to set the
gpcdeltauppergpc Mode or Fixed gpcdeltauppergpc Mode to On.
92 No active marker
Due to the fact that marker is not displayed, the command which has been sent was
ignored. For example, during when the marker is not displayed,
CALC{1-5}:MARK:SET
command on page 336 was used in attempt to change the equipment setting of the E4991A.
First use CALC{1-5}:MARK{1-8} command on page 304 to show marker on the display.
94 No fixed delta marker
Due to the fact that reference marker is not set in fixed gpcdeltauppergpc mode, the
command which has been sent was ignored. For example, during when the fixed
gpcdeltauppergpc mode is not set,
CALC{1-5}:MARK:REF:Y command on page 335 is
used in attempt to set the reference marker to the designated measurement rates.
First, use CALC{1-5}:MARK:REF command on page 328 to display the reference
marker. Next, use CALC{1-5}:MARK:REF:TYPE command on page 333 to change the
setting to fixed gpcdeltauppergpc mode.
95 Frequency sweep only
A command only valid during the sweep parameter is in frequency has been sent. For
example, during when the sweep parameter is set other than the frequency,
CALC{1-5}:MARK:UNIT command on page 337 is used in attempt to set the marker
X-axis display to relaxation time (1/2πf).
First, use SWE:TYPE command on page 515 to set the sweep parameter to frequency.
