Table C-2. Reasons for Differences
HP/Keysight Series 6050x
70 milliseconds (typical)
If external equipment is connected to the load, the decreased command
execution time of the N3300A Series loads may not allow sufficient settling
time for the equipment under test. You may need to insert wait statements in
your program if the equipment under test requires a certain amount of
settling time after a load change before a measurement can be made.
1 range (model dependent):
0-60 volts or
0-150 volts or
0-240 volts
The addition of voltage programming and readback ranges provides 16-bit
accuracy with the N3300A Series loads. Existing programs may need to be
modified to take advantage of the improved accuracy provided with the
additional ranges.
1 range (model dependent):
0-10 amps or
0-30 amps or
0-60 amps or
0-120 amps
The addition of current readback ranges provides greater accuracy with the
N3300A Series loads. Existing programs may need to be modified to take
advantage of the improved accuracy provided with the additional ranges.
Single measurement occurs at
command execution.
This feature provides greater accuracy and noise immunity when making
measurements. The time required to make measurements with the N3300A
Series loads may vary considerably, depending on the type of measurement
specified. The default measurement settings on the N3300A Series loads
are faster than measurements on previous electronic loads.
Voltage (60V) = 0.1% +50mV
Current (60A) = 0.1% +75mA
Resistance (1Ω) = 0.8% +8mΩ
Resistance (100Ω) = 0.3% +8mS
Resistance (10kΩ) = 0.03% +8mS
This feature provides greater accuracy with the N3300A Series loads.
Existing programs may need to be modified to take advantage of the
improved programming accuracy provided with the additional ranges.
Voltage (60V) = 16mV
Current (60A) = 16mA
Resistance (1Ω) = 0.27mΩ
Resistance (100Ω) = 0.27mS
Resistance (10kΩ) = 0.027mS
This feature provides greater accuracy with the N3300A Series loads.
Existing programs may need to be modified to take advantage of the
improved programming resolution.
Keysight Series N3300A

2 ranges (model dependent):
0-6, 0-60 volts or
0-15, 0-150 volts or
0-24, 0-240 volts
2 ranges (model dependent):
0-1, 0-10 amps or
0-3, 0-30 amps or
0-6, 0-60 amps or

Multiple measurements at command
execution. Average value is returned.
Number of samples and time interval
between samples is programmable.
Voltage (60V) = 0.1% +8mV
Current (60A) = 0.1% +15mA
Resistance (2Ω) = 0.4% +12mΩ
Resistance (20Ω) = 3% +40mΩ
Resistance (200Ω) = 20% +120mΩ
Resistance (2kΩ) = -50% +2000%
Voltage (60V) = 1mV
Current (60A) = 1mA
Resistance (2Ω) = 0.035mΩ
Resistance (20Ω) = 0.35mΩ
Resistance (200Ω) = 3.5mΩ
Resistance (2kΩ) = 35mΩ
