3 large-size display
windows ( DATA1 ) |
|
|
Adopted large displays making measured or setting value
easy to look.
It is convenient to 3 displays at one time.
Measured value is high resolution of 4 1/2 digits.

dB, % display |
|
|
| In addition to the ratio measurement that is convenient
for the relative measurement, the percentage (%) display and the
decibel (logarithmic ratio) display which effectively evaluate the
signals changing largely, are available.

Noise measurement |
|
|
Equipped noise measurement mode that can measure the
noise density. Measurement range of noise density:
| Voltage : |
20nV/ √Hz to |
|
1V/ √Hz full-scale |
| Current : |
100fA/ √Hz to |
|
1µA/ Hz full-scale |

Voltage / Current
range |
|
|
| Voltage sensitivity : |
2nV full-scale to 1V full-scale
|
| Current sensitivity : |
5fA full-scale to 1µA full-scale |

Filter |
|
|
Line filter effectively eliminating the ham noise.
Also it can set not to use anti-areas filter (THRU) for super
high-speed response.

Auto set |
|
|
| Each setting of sensitivity, time constant, dynamic
reserve and phase is automatically set to the optimum value of that
time.
