Measuring Procedure

Frequency Measurement
  1. Push the “Power Switch” (3-13, Fig. 1), all the display segments will bright then show 0 or some random values. Now the instrument is ready for measurement.
    Considering:
  • If no signal input (or short circuit), for “Period Range” the display will show B”——oL——-”

  • If no signal input (or short circuit, for “10 MHz Range” the display will show “0”.

  • If no signal input (or short circuit, for “100 MHz and 2,7 GHz Range “the display will show certain random value due to the environment noise for input circuit, it is normal. However after the signal input, those noise will be suppressed 2. Push the “Range Switch” (3-15, 3-16, 3-17, Fig. 1) to the “10 MHz”, “100
    MHz” or “2,7 GHz” position according to the measurement required.
    Considering:
    Always to select the suitable range to get high sensitivity & good resolution.

    1. Input the measured signal to Channel A/BNC socket (3-2, Fig. 1) via BNC cable (optional, PB-21 or BB-22) if the measured frequency is within 10 MHz.
      Input the measured signal to Channel B/N type socket (3-3, Fig. 1) via N type cable (optional, NN-23) if the measured frequency is within 10 MHz to 100 MHz.
      Input the measured signal to Channel C/N type socket (3-4, Fig. 1) via N type cable (optional, NN-23) if the measured frequency is within 100 MHz to 2700 MHz.

    2. According the different input range, select the Sensitivity Switch (3-19, 3-20, 3-21, Fig. 1) to the “HIGH” (high sensitivity) or “NORMAL” (normal sensitivity) position.

    3. Slide the Gate Time Switch (3-18, Fig. 1) to the “FAST” or “SLOW” position to determine the convenient sampling time & display resolution.

    4. The display unit is Hz for 10 MHz range. The display unit is MHz for 100 & 2,7 GHz range. The Gate Indicator (3-22, Fig. 1) will be flashed one for each sampling time passed.
      Considering:

  • Select to “Gate Time Switch” to “FAST” position normally.

  • If select to “SLOW” position, then push the RESO. button (3-10, Fig. 1) at once 3 times will result 3 kinds Sampling Time & Resolution combination. For more details please see the following table:

Data Hold Measurement

During the measurement, it will hold the display values, if push the “HOLD Button” (3-8, Fig. 1) at once.

Considering:

  • When push the HOLD button at once, then the display will show “- – – HOLD – – -” & holding values alternately.
  • It will release the hold function if push the HOLD button at once again.
Relative Measurement
  1. During the measurement, the circuit will memorize the last measured values if push the “REL. Button” (3-9, Fig. 1) at once, then LCD will show “0” & a “REL” marker appears on the right down corner.
  2. The new measured frequency values will deduct above memorized “last measured values” automatically.
  3. It will release the Relative Measurement function if push the REL. button at once again, at same time the “REL” marker will disappear.

Considering:
When marking the “Data Hold” & “Data Record” measurement, the Relative function is prohibited.

Data Record (Max., Min., Average reading)
  1. The DATA-RECORD function displays the maximum, minimum and average readings. To start the DATA RECORD function, press the RECORD button once. An “R.C.” marker should appear on the top right corner of the display.
  2. Push the RECALL button once and “- – -HI- – -” should appear on the display followed in about a second by the maximum reading. The “R.C.” marker will be flashing.
  3. Push the RECALL button again and “- – -Lo- – -” should appear on the display followed by the minimum reading.
  4. Push the RECALL button again and “- – -A- – -” should appear on the display followed by the average reading. The average reading will be continually updated every ten samples.
  5. Push the RECALL button again will stop the “R.C.”, marker from flashing and normal reading will be.
Period Measurement
  1. Input the measured signal to Channel A/BNC socket (3-2, Fig. 1) via BNC cable (optional, PB-21 or BB-22)
  2. Select the “Period Switch” Switch (3-14, Fig. 1). Select the “10 MHz range Sensitivity Switch” (3-19, Fig. 1) to the “HIGH” (high sensitivity) or “NORMAL” (normal sensitivity) position. * To select the “HIGH” sensitivity normally.’
  3. Slide the Gate Time Switch (3-18, Fig. 1) to the “FAST” or “SLOW” position to determine the convenient sampling time & display resolution. * To select the “FAST” gate time normally.

Consideration:

  • The input frequency range for period function is from 10 Hz to 10 MHz.
  • The display will show 5 digits then following the unit: ” – s” represent milli ­ seconds “us” represent micro – seconds
  • The principal of period display is calculated from the measured frequency (Hz), the formulas are following:
  • The period range accuracy are based on the digit No. + 1 (max. 5 digits) of measured frequency. For example if measured frequency is 615 Hz (3 digits), then the period values accuracy will be on the leading four digits (1.626 mS).
  • If no signal input (0 Hz), the display will show over range (- – – oL – – -).
Over Range Indicator

The Display will show the over range indicator “- – – oL – – – ” along with the “BIBI…” sound, if

  • Input signal frequency over 10 MHz for 10 MHz range.
  • Input signal frequency over 100 MHz for 100 MHz range.
  • Input “0 Hz” for the period range.
