Measurement Sensitivity and Vertical Axis Effective Range

When the measurement sensitivity is set to NORMAL HOLD, the internal amplifier has
a fixed gain. Five different gains are set automatically according to the reference (REF)
level setting. However, the effective range of measurement data is limited to the following
range, using the reference (REF) level (dBm) as a reference.

REF-20 dBm < (effective range) < REF+10 dBm

If the level scale is set to 10 dB/DIV, the display would exceed the effective range, so the
areas at 10 dB from the screen stop and 20 dB from the bottom are inaccurate.
When measurement sensitivity is set to NORMAL HOLD, we recommend setting the
level scale to 5 dB/DIV or less.
Under the measurement sensitivity settings NORMAL AUTO, MID, and HIGH 1 to 3,
an automatic gain is used, permitting measurements over a wide level range through a
single sweep. Select the appropriate sensitivity level based on the light reception level
required for the particular measurement application.

Stray Light from the Monochromator

The instrument has a newly designed, high-performance monochromator. Depending
on the measurement conditions, stray light at a level 30 to 50 dB below the original
spectrum, as well as other stray light specific to the monochromator may occur in
wavelength areas 100 to 200 nm from the peak wavelength. If this stray light is likely to
have a severe impact on measurements, the sensitivity can be set to HIGH 1 to 3 and
CHOP MODE can be set to CHOP or SWITCH in order to reduce the effects of the stray
light.

Measurement according to the

stray light.

Stray light suppression ratio:

40 dB or more

Measurement time is rapid

even for high sensitivity

measurements.

Since the stray light is

also measured, the low

level component is not

accurate if the light source

is of high power.

SWITCH

Two sweeps per measurement

are performed. The first sweep

measures the stray light

component, and high dynamic

measurement is possible

through subtraction.

Stray light suppression ratio:

60 dB or more

Short-duration

measurement can be taken

with stray light removed.

If the measurement

duration is long, it is

influenced by temporal

changes in the measured

light.
