    HPS50 PersonalScope Meter readout READOUT SET-UP Press to call the meter 1 to 4 selection menu. Make use of the cursorkeys to set a readout for up to 4 meters Setting up the measurement readouts: 1. Pressing the ‘meter’-key selects the first readout location.
  • Page 15 HPS50 PersonalScope Meter readout 1. DC voltage measurement (V=). This function enables the user to measure DC voltages (only for DC input coupling) 2. Maximum voltage (Vmax.). The signal's positive peak voltage (difference between zero and highest value) is displayed. 3.
  • Page 16 HPS50 PersonalScope Meter readout 6. dBV measurement (dBV ac). The measured signal (ac only) is converted to dBv (0dB= 1V). 7. dBm measurement (dBm ac). The measured signal (ac only) is converted to dBm (0dB= 0.775V). 8. dB measurement (dB ac). The measured signal (ac only) is converted to dB (0dB= dBref*) 9.
  • Page 17 HPS50 PersonalScope Meter readout Audio power calculation. The measured voltage is converted into power, suposing that the voltage is measured across an impedance. The calculated power can be displayed for loads of 2, 4, 8, 16 or 32 Ohm. To choose the different loads, first highlight the power readout and then press the right cursor key.
  • Page 18 HPS50 PersonalScope Meter readout Notes: • If the signal goes off-screen or when the signal is too small for measurement, the readout will show ??? (see fig 28) • For all AC measurements: Make sure that at least one or two periods are displayed or Fig 28 select the auto-setup function.
