Item Description
Turn the Edit knob to the right to increase the output value of the active-edit digit.
Turn the Edit knob to the left to decrease the output value of the active-edit digit.
Error mode / edit keys
moves the active-edit digit one decimal place to the left.
switches the active-edit field between the amplitude and frequency.
moves the active-edit digit one decimal place to the right.
Front USB port. Calibration report data can be saved to a flash drive inserted into
this port. The Calibration report process is explained in Chapter 7.
Multiplier keys
- multiplies the present output by 10.
- divides the present output by 10.
Invert output key. If the output function is dc voltage, current, ac voltage entered in
dBm, or a wideband output entered in dBm, push
to toggle the
polarity of the output. If the output function is ac voltage or current, push
to change the output to dc.
GROUND
Binding Post
If the Calibrator is the location of the ground reference point in a system, the
GROUND binding post can be used to connect other instruments to earth ground.
The chassis is normally connected to earth ground through the three-conductor line
cord instead of through the earth ground binding post. Refer to "Cable Connection
Instructions" in Chapter 4 for details. Included with the Calibrator is a brass strap
that connects GROUND to V GUARD.
V GUARD
Binding Post
[1]
The V GUARD binding post provides an external connection point for the internal
voltage guard. For a UUT with floating (ungrounded) inputs, the V GUARD should
be connected to LO internally (External Guard OFF). For a UUT with a grounded
input, the V GUARD must be externally connected to the grounded UUT input
(External Guard on). The maximum allowable potential between the V GUARD
connector and chassis ground is 20 V peak. Refer to "When to use the External
Voltage Guard" and "Cable Connection Instructions" in Chapter 4 for details.
WIDEBAND
Connector
[1]
The WIDEBAND connector is a Type "N" connector that provides a connection
point for output from the Option 5730A/03 or 5730/05 Wideband AC Module.
Wideband output specifications are stated for output levels present at the end of its
3-foot 50 Ω coaxial cable terminated into a 50 Ω purely resistive load. The
connector shell is connected to chassis ground. Refer to Chapter 4 for connecting
and operating instructions for the wideband module.
