Programming Basics
Data Output Format
Data Resolution
The 4 bytes binary data format provides the following data resolution. To use this
data format, enter the FMT3 or FMT4 command. The resolution of the SMU
measurement value will be larger than the measurement resolution of the B1500’s
high resolution A/D converter. For Range value, see “4 Bytes Data Elements” on
page 1-41.
• SMU measurement value (voltage or current): Range / 50000
• SMU output value (voltage or current): Range / 20000
• CMU measurement value (resistance or reactance): Range / 2
12
• CMU measurement value (conductance or susceptance): 1 / (Range × 2
12
)
• CMU oscillator level monitor value (Vac), DC bias monitor value (Vdc),
frequency (Hz): Range / 50000
• CMU DC bias output value: 2 mV
The 8 bytes binary data format provides the following data resolution. To use this
data format, enter the FMT13 or FMT14 command. For Range value, see “8 Bytes
Data Elements” on page 1-48.
• SMU measurement/output value (voltage or current): Range / 1000000
• CMU measurement value (resistance or reactance): Range / 2
24
• CMU measurement value (conductance or susceptance): 1 / (Range × 2
24
)
• CMU oscillator level monitor value (Vac), DC bias monitor value (Vdc),
frequency (Hz): Range / 1000000
• CMU DC bias output value: 1 mV
