Perform Self-Calibration

WARNING
When performing self-calibration, no signal is injected into the handheld scope. During the self-calibration process, the firmware will perform zero, offset, and TDC calibration.
– For zero calibration, the firmware will acquire samples for a fixed period of time
corresponding to the zero input condition. The acquired data contains channel noise and DC offset. The firmware determines this channel DC offset and upon completion of self-calibration, uses the determined DC offset to subtract from ADC samples, producing offset-compensated samples. This feature is useful for removing channel DC offset due to temperature changes and component aging, thus providing better accuracy.
–Offset calibration (performed after completion of the zero calibration)
calibrates the system offset DAC for gain accuracy. During calibration, the firmware determines the offset DAC code settings required to offset the zero input signal trace to +4 divisions and –4 divisions (vertical). The codeword range for the offset DAC to move the zero input trace across ±4 division range will represent the offset DAC gain. This gain changes due to temperature variation and component aging. Offset calibration corrects for this drift in the offset DAC gain.
– TDC calibration calibrates and corrects for errors (due to temperature
variation) in the time interval measurement performed by the TDC circuit.
Allow the handheld scope to warm up for at least 30 minutes before performing self-calibration. It is recommended that you perform self-calibration in the following situations:
Getting Started 1
Keysight U1610/20A User’s Guide 25
– Every 12 months or after 2000 hours of operation. – If the ambient temperature is >10 °C from the calibration temperature.
– To maximize the measurement accuracy.
– After experiencing abnormal operation.
– To verify proper operation after repairing.
Disconnect all probe and meter connections to the input terminals of the handheld scope before performing self-calibration.

Independently Isolated Scope Input Channels

There are two main categories of signal sources:
– Earth ground referenced signal—the voltage signals are referenced to a system
ground, such as earth ground.
– Floating ground referenced signal—a floating signal in which the voltage signal
is not referenced to earth ground.
Figure 1-5 Floating ground reference signal and earth ground
reference signal
When measuring floating signals with instruments that have multiple inputs, unwanted ground loops may occur. These ground loops can induce measurement errors and cause electrical shock or power surges. Ground loop occurs between the negative terminals of two inputs as shown in Figure 1-6.
Instruments with channel-to-channel isolation can be used to eliminate the ground loops. Isolated channels separate the two signal path effectively from each other by eliminating any potential common circuit path between the two inputs.

Figure 1-6 Ground loop
The handheld scope input channels, external trigger, USB, and AC/DC adapter are electrically isolated from each other. This level of isolation allows you to:
– measure floating signal between channels without any unwanted ground loops.
– latch trigger points freely on the circuit.
– connect to the PC using the USB port for monitoring as the port is isolated
from the handheld scope.
– monitor your device-under-test while charging the handheld scope.
Figure 1-7 outlines the handheld scope channel isolation. The chassis and the
controls of an isolated-input channel are designed with plastic, rubber, or other types of insulating material. Each input channel (CH1, CH2, and Ext. Trig) is isolated with Keysight isolation technology architecture and the ground leads are referred to any ground potential as shown in Figure 1-7.

Floating measurement with isolated probes at CAT III 600 V

Before performing floating measurements with the handheld scope, ensure that the measured signal is within the voltage range specified on the probe and input terminals, and the floating voltage from any terminal to ground as shown in
Figure 1-10.
The differential signal in each channel is referenced to a reference point that is not connected to the earth ground. This helps in eliminating ground loop errors.
Figure 1-10 Channel-to-channel isolation at CAT III 300 V
The maximum input voltage on each BNC input is CAT III 300 V (referenced to non-earth grounding and referenced to earth-grounding). If you are measuring an input floating voltage of CAT III 600 V with a 10:1 probe, the signal will be attenuated 10 times. The actual voltage flow into the BNC input will be CAT III 60 V, which is within the maximum input voltage rating.

NOTE
RMS (AC)
AC voltage is normally expressed as a root-mean-square (RMS) value, represented as Vrms. For a sinusoidal voltage, Vrms is equivalent to Vpeak/√2.
RMS (DC)
VRMS (DC) is the RMS value of the waveform over one or more full periods.

Power measurements

Power measurement is a point-by-point multiplication of the voltage and current waveforms measured by the voltage and current probes.
The U1610/20A is designed to measure power factor, active power, reactive power, and apparent power in the electrical power distribution system in factories or commercial and residential areas. It is ideally suited to measure power in the 50 Hz or 60 Hz cycle commonly found in the power distribution system.
For higher frequency applications such as those found in switch mode power supplies, a deskewing mechanism is needed in order to compensate for the time delay between the voltage and current probes.
This is important as a small offset in the timing of the high frequency voltage and current traces can cause a large error in the instantaneous power reading. The U1610/20A is not able to support this high frequency power measurement application.
Ensure that the correct attenuation factor/sensitivity is set for the connected voltage/current probe respectively. Refer to page 69 for more information in setting up the probes.
74 Keysight U1610/20A User’s Guide
Using the Oscilloscope 3
NOTE
Active Pwr
Active power (real or true power) is measured in watts (W) by averaging a portion of power over a complete cycle of the AC waveform which produces a nett transfer of energy in one direction. It is the power drawn by the electrical resistance of a system.
Apparent Pwr
Apparent power is measured in volt-amperes (VA) and by the vector sum of the active and reactive power. It is the voltage on an AC system multiplied by all the current that flows in it.
Reactive Pwr
Reactive power is measured in volt-amperes reactive (VAR) and is the portion of power stored and discharged by inductive motors, transformers, and solenoids.
Pwr Factor
Power factor is a measurement of how effectively the electrical power is being used. A high power factor (near 1.0), indicates the efficient utilization of the electrical power, while a low power factor indicates the poor utilization of the electrical power. If the power factor falls below 0.90, some utility companies charge a power factor penalty. Power factor is the ratio of real power (watts) and the apparent power (volt-amperes). It is calculated by dividing the real power with the apparent power.
Keysight recommends the U1583B AC current clamp for the power measurement.

To run or stop multimeter measurements, press .
To select the measurement function, press and use the keys.
Press again to exit the selection menu.
When you measure voltage, the AC ( ), DC ( ), or AC+DC ( ) indicator is displayed. A voltage warning sign ( ) will appear whenever a potentially hazardous voltage is being measured.
The virtual scale indicates the measured value and the average, maximum, and minimum values. This allows you to quickly estimate different attributes of the input, such as variability (difference between min and max) and stability (average reading versus current reading).
If there is an input overload, OVERLOAD will be shown and no readings will be displayed.
For accurate measurement results, allow the multimeter to warm up for 30 minutes.

Voltage Measurements

WARNING
DC
Ensure that the probe tips are in contact with the metal contacts inside the outlet. Improper contact may lead to inaccurate voltage measurement. Poor contact will cause inaccurate readings and poses a risk of electrocution.
Voltage measurements consist of:
– V AC – Measurements are returned as true RMS readings, which are accurate
for sine waves and other waveforms (with no DC offset).
– V DC – Measurements are returned with their polarity.
– V AC+DC – Both AC and DC signal components are measured as one AC+DC
(RMS) value combined.
To measure voltage:
1 Press and use the keys to select the voltage measurement
function. Set up the following connections:

Resistance Measurement

Disconnect power to the device-under-test and discharge all high voltage capacitors to avoid electric shock and damage to the handheld scope or device-under-test while taking resistance measurement.
Resistance (Ω) is measured by sending a small current out through the test leads to the device or circuit-under-test.
To measure resistance:
1 Press and use the keys to select the resistance
measurement function. Set up the following connections:
