When the desired calibration level is reached, STORE
REF LVL may be pressed to store the new value in
nonvolatile memory. If STORE REF LVL is not pressed,
the new value remains in use until a power-on occurs.
Front-panel key access:
Introduces an offset to all amplitude readouts (for
REF LVL OFFSET
example, reference level and marker amplitude). It
does not change the position of the trace on-screen. The
offset is in dB, regardless of the selected scale and
units. The offset can be useful to account for gains or
losses in accessories connected to the input of the
analyzer. To enter an offset value, use the data keys,
the step keys, or the knob. When this function is active,
an R appears on the left edge of the display.
Front-panel key access:
Adjusts the resolution bandwidth. The bandwidth,
RES BW AUTO MAN
which appears in the active function block, ranges from
1 Hz to 2 MHz in a 1, 3, 10 sequence. The value can be
changed using the data keys, the step keys, or the knob.
A line under AUTO or MAN indicates whether the
bandwidth is coupled (AUTO) or is in manual mode
(MAN). When the resolution bandwidth is in manual
mode, press RES BW AUTO MAN until AUTO is
underlined to return the bandwidth to coupled mode.
Front-panel key access:
Displays the sampling-oscillator frequency
SAMPLER FREQ
corresponding to the current start frequency. It also
displays the loop bandwidth compensation value
(established during local oscillator calibration) for the
sampler frequency. This value is displayed below the
sampler frequency and is preceded by a "#" sign.
Front-panel key access:
SAMPLER HARMONIC
corresponding to the current start frequency.
Front-panel key access:
Accesses a menu of softkeys that allow you to save
SAVE
instrument-state data and trace data. These softkeys
are as follows: SAVE STATE, PWR ON STATE, SAVE
TRACE A, SAVE TRACE B, SAVELOCK ON OFF, and
SAVE PRSEL PK.
