mmWAVE ALC CAL Menu – Millimeter-Wave Automatic Level Control Calibration

Type of Leveling Button Group Start

The IF, RF, and VNA buttons at the top of the menu form a button selection group where only one type of leveling can be selected.

If the IF type of leveling is selected, it provides the advantages of RF leveling described below plus the benefit of greater power control range and a lower minimum leveled power (at least 20 dB lower typically). As one approaches a 100 MHz difference between source and receiver frequencies, the power control range will start to decrease as will power control accuracy. The use of IF leveling is not recommended for source-receiver frequency differences greater than 100 MHz.

If the RF type of leveling is selected, it provides a leveled RF output power with improved source match, protection against over powering the DUT, and insuring that the DUT is operating in its designated power range.

VNA

If the VNA type of leveling is selected, it turns the RF or IF ALC off and the ALC accuracy is set as that for the standalone VNA instrument.

Type of Leveling Button Group End

The VNA button is the end of the Type of Leveling button group.

Navigation

There are multiple paths to this dialog box depending on the instrument model number and the equipped options:

EXTERNAL MODULE SELECTION Dialog Box

1. At top, the OML tab is selected and the available OML Modules are shown. Select a module radio button configure that module.	2. At bottom, the VDI tab is selected and the available VDI Modules are shown. Select a module radio button to configure that module. Note that VDI modules have two basic types at -20 G and -40G. The module type selected here must match the module being used as the two types have slightly different frequency plans.

External Module Summary Notes

• WR Numbers

The WR number abbreviation is for “rectangular waveguide” using English measurement units. The interior dimensions of waveguides have an aspect ration of 2:1, where the broadwall is twice the dimension of the narrow wall. The number following is approximately the broadwall length in mils (0.001 in) divided by 10. For example, the WR-62 waveguide has a broadwall dimension of 620 mils (0.620 in) divided by 10 which yields 62. The larger the WR Number, the lower the operating frequency range. Both OML Modules and VDI Modules reference WR and the equivalent WM Numbers.

• WM Numbers

WM numbers are an emerging metric specification for equivalent and new waveguides using metric measurements. The interior opening aspect ratio follows the same 2:1 ratio. The number is derived from the broadwall dimension in micrometers (µm or 0.0001 m). For example, the WM-570 has a broadwall dimension of 570 µm. The larger the WM Number, the lower the operating frequency range. Both OML Modules and VDI Modules reference both WR and the equivalent WM Numbers.

• Anritsu Numbers

Anritsu has the following five Broadband/Millimeter-Wave module numbers:

• MA25300A Millimeter-Wave Module, 54 to 145 GHz – Requires a MS4647A VNA with Broadband/Millimeter-Wave Option 08x and a 3739C Test Set. Two MA25300A modules are required.

• 3743A Millimeter-Wave Module, 54 to 125 GHz – Requires a MS4647A VNA with Broadband/Millimeter-Wave Option 08x and a 3739x Test Set. Two 3743A modules are required.

• 3744A-EW/SM6597 Millimeter-Wave Module, W-Band, 65 to 110 GHz – Requires any MS464xA Series VNA equipped with Millimeter-Wave Option 08x and a Millimeter-Wave Test Set.

• 3744A-EE/SM6499 Millimeter-Wave Module, E-Band,56 to 95 GHz – Requires any MS464xA Series VNA equipped with Millimeter-Wave Option 08x and a Millimeter-Wave Test Set.

• 3743A-Rx; This module is typically ordered as an accessory to the ME7838 system. When ordering this module, the base VectorStar VNA must have Noise Figure Option 041.


Note	When using MA25300A BB/mm-Wave modules, the 3739C Test Set is required.
