Z5623A Option H83
Description
Description
The Agilent Z5623AH83 is a 2 GHz to 20 GHz dual directional pulse test set.
When connected to the E8362B Series Network Analyzer with Option H08 (Pulse) and
H11 (IF access) allows pulse measurements to be made from 2 GHz to 20 GHz for both the
forward and reverse parameters. The Z5623AH83 can be configured in many ways.
The Bypass configuration allows the E8362B Series Network Analyzer to be used from
10 MHz to 20 GHz depending on the analyzer. This mode bypasses the test sets internal
2 GHz to 20 GHz PIN modulator switch. In the Pulse mode the user can configure the test
set for their application needs, such as straight un-condition pulse measurements or
permit the insertion of high power amplifiers and other signal conditioning equipment.
This allows high power measurements at RF levels up to 20 Watts (+43 dBm) from 10 MHz
to 20 GHz. This document details a step by step procedure to configure the test set for high
power operation.
Control of the Agilent Z5623AH83 Dual Directional Pulse Test Set can be performed either
by GPIB or directly. Both methods control the Port 1 and 2 internal switches and
attenuators. Direct control requires the user to connect to two 37-pin D-Sub connectors
that are located on the rear panel. Both GPIB and direct control cannot be used
simultaneously. When used in the direct control mode the test sets front panel LCD
indicator may differ from the user setup.
High power configurations require that attenuators and isolators be connected to the test
ports and receivers to protect the E8362B. The Agilent E8362BH85 High Power
Configurable PNA Series Network Analyzer when ordered with the Option H08 and H11
can be used for high power pulse measurement applications. More information on the
setup and configuration can be found in the E8362B, E8363B and E8364B Option H85
User’s and Service Guide Supplement (E8364-90027).
Information regarding the PNA Option H08 and H11 can be found in the PNA online help
system.
The instrument is shipped from the factory with jumper cables installed on the front panel
in what is called the Shipped Configuration. Refer to Figure 10 on page 15.
Two high pass filters (Z5623-80027) have been provided with the Test Set. These filters are
used externally to eliminate video feed through from the PIN switch. The filters are used
for measurements in the range of 2 GHz to 20 GHz.
The pulse test set can be used from 400 MHz to 2 GHz but is not specified. No band pass
filters are provided for this frequency range. If low frequency pulse measurements are
required the user must supply the necessary high pass filter.

Video Feedthru
Video Feedthru
Video leakage refers to the spurious signals present at the RF ports of the switch when it is
switched without an RF signal present. Refer to Figure 1. These signals arise from the
waveforms generated by the switch driver and, in particular, from the leading edge voltage
spike required for high speed switching of PIN diodes. When measured into a 50 Ω system,
the magnitude of the video leakage can be as much as several volts. The frequency content
is concentrated in the band below 250 MHz, although measurable levels can be observed as
high as several GHz. The magnitude of the video leakage can be reduced significantly by
adding a high pass filter in the RF path Pulse Out to Filter In. Refer to Figure 2. The
picture below shows the leading and trailing edges of video feedthru.

Electrostatic Discharge Protection
Electrostatic Discharge Protection
Protection against electrostatic discharge (ESD) is essential while removing assemblies
from or connecting cables to the network analyzer. Static electricity can build up on your
body and can easily damage sensitive internal circuit elements when discharged. Static
discharges too small to be felt can cause permanent damage. To prevent damage to the
instrument:
• always have a grounded, conductive table mat (9300-0797) in front of your test
equipment.
• always wear a grounded wrist strap (9300-1367) with grounding cord (9300-0980),
connected to a grounded conductive table mat, having a 1 MΩ resistor in series with it,
when handling components and assemblies or when making connections.
• always wear a heel strap (9300-1126) when working in an area with a conductive floor.
If you are uncertain about the conductivity of your floor, wear a heel strap.
• always ground yourself before you clean, inspect, or make a connection to a
static-sensitive device or test port. You can, for example, grasp the grounded outer shell
of the test port or cable connector briefly.
• always ground the center conductor of a test cable before making a connection to the
analyzer test port or other static-sensitive device. This can be done as follows:
1. Connect a short (from your calibration kit) to one end of the cable to short the center
conductor to the outer conductor.
2. While wearing a grounded wrist strap, grasp the outer shell of the cable connector.
3. Connect the other end of the cable to the test port and remove the short from the
cable.

Operation
The Agilent Z5623AH83 Dual Directional Pulse Test Set can be configured differently for
many applications. Included in this document are three typical configurations:
• Figure 10, “Shipped Configuration.”
• Figure 12, “High Power Forward Direction.”
• Figure 13, “High Power Dual Directional.”
NOTE
The internal firmware of the PNA has not been modified for this test set
option. The power levels indicated on the Agilent E8363B and E8364B may
differ depending on the user configuration that is chosen.
Refer to the configuration diagrams for external component connections and/or operating
constraints when utilizing the high power capability of the Agilent Z5623AH83 Dual
Directional Pulse Test Set. External components are not supplied with this option.
When using the Agilent E8362B Series Network Analyzer with Z5623AH83 Dual
Directional Pulse Test Set in the bypass or the high power configuration, the PNA
Frequency Offset mode (Option 080) and External R1 (Option 081) must be activated. This
will ensure phase lock and allow R1 and R2 to receive the new reference power levels from
the amplifiers. Refer to Table 3 on page 14.
CAUTION
The Z5623AH83 is equipped with reference channel attenuators. These
attenuators reduce the RF power to the PNA R1 and R2 receiver ports. The
test set attenuators can be set from 0 to 60 dB in 10 dB steps. The
recommended power levels to the PNA R1 and R2 receiver ports is –15 dBm.
Refer to your PNA specifications to optimize power levels to the receiver
ports.
The PNA Option 016, Receiver Step Attenuators, reduces the power to the A
and B receivers. The A and B maximum attenuator setting is 35 dB. Power
measurements to Test Ports 1 and 2 above +35 dBm will require additional
attenuation. Add the appropriate amount of attenuation that will keep the
coupler arm output power below –15 dBm. Refer to Table 3 on page 14.
CAUTION
Hot Switching is not allowed with the Z5623AH83 when making high power
measurements or damage to the switch will occur. Hot Switching is the
condition when the internal switch or switches are set to a position for
making high power measurements, and then set to another position without
reducing the power. The maximum power that the switches are allowed to
switch states is +20 dBm.

Controlling the Test Set
Controlling the Test Set
The Agilent Z5623AH83 is considered a “slave” instrument. A Controller must be used to
control the test set. There are four ways to control the test set:
• The PNA can be used as the controller to talk to the test set over the GPIB.
• A Controller can directly talk to the test set over the GPIB.
• The Parallel port can be used to set the test set.
• Direct control access to the internal switches and attenuators via open collector lines
to ground the input lines.
Commands
As mentioned before, the test set can be controlled in four ways. The first two involve the
use of a separate computer. The third way uses parallel port manually. The fourth control
method uses direct access from two rear panel 37 pin D-Sub connectors.
NOTE
The 37 pin D-Sub jumpers (Z5623-60202) must be attached to the test sets
Port 1 and 2 rear panel direct access connectors for the GPIB and parallel
port commands to work. These connectors are not connected to the test set
when they are shipped.

If you are using National Instruments VISA, be sure to set the variables as follows:
VI_ATTR_SEND_END_ENVI = FALSE ‘ This specifies whether to assert END during the
transfer of the last byte of the buffer.
VI_ATTR_TERMCHAR = 0x0A ‘ This is the termination character. When the termination
character is read and VI_ATTR_TERMCHAR_EN is enabled during a read operation, the
read operation terminates.
VI_ATTR_TERMCHAR_EN = VI_TRUE ‘ This is a flag that determines whether the read
operation should terminate when a termination character is received.
VI_ATTR_SUPPRESS_END_EN = VI_FALSE ‘ This specifies whether to suppress the
END bit termination. If this attribute is set to VI_TRUE, than the END bit does not
terminate read operations. If this attribute is set to VI_FALSE, than the END bit
terminates read operations.
Write Commands:
Append all commands with \n. For example; *rst\n
Read Commands:
The test set returns data terminated by \r\n. For example the query sw10?\n returns
00000010\r\n.
Parallel Port
The third way is used by the service center or during production to verify the port path
connections. This uses the parallel port on the rear panel of the Z5623AH83. This method
uses an 8722ES Network Analyzers Parallel port to control the test set. The following
example assumes that the address of the network analyzer is set to 16. Be sure to use an
ending semi-colon.
OUTPUT 716;"PARALGPIO" (Sets the parallel port for GPIO function).
OUTPUT 716;"PARAOUT[D]; (Programs all GPIO output bits (0 to 256) at once).

Controlling the Test Set
Direct Control
The fourth method to control the test set uses the Port 1 and Port 2, 37 pin D-Sub
connectors located on the rear panel. Removing the jumper connectors (Z5623-60202) will
allow the user to control the internal switches and attenuators. Refer to Table 5 on page 40
which shows the pinout and function for Port 1 and Port 2.
NOTE
LCD indicator is only valid when the test set is used in control methods; PNA,
Controller, and Parallel. Direct control does not change the LCD indicator
when either the switches or attenuators are repositioned.
Controlling the Switches
Control of the internal switches directly, is provided from the 37 pin D-Sub connector and
can be done in two ways.
• TTL
• Open Collector
The TTL input allows the user independent switch position control by either a low (0) or
high (1). The TTL voltage is 0 or 5 volts. The Figure 30 on page 37. The 37 Pin D-Sub
connector shows the rear panel input/output configuration for Port 1. Port 2 is identical to
Port 1 but where SW1 is replace by SW4, SW2 is replace by SW5, SW3 is replace by SW6
on the RF block diagram. Pins 5, 12, 22 are the TTL input pins. Pin 5 controls SW1 or
SW4, pin 12 controls SW3 or SW6, and pin 22 controls SW2 or SW5.
The Open Collector inputs allows the user to control a switch position by grounding either
the A (AD) or B (BD) dive input lines for each switch. Only one of these two input lines can
be grounded at any given moment. Recommended is break before making when the input
line position changes. Refer to Figure 30. The 37 Pin D-Sub connector shows the rear panel
input/output configuration for port 1. Port 2 is identical to port 1 but where SW1 is replace
by SW4, SW2 is replace by SW5, SW3 is replace by SW6 on the RF block diagram. Pins
(1,2), (8,9), and (25,26) are the A and B drives input pins. Pins 1, 2 control SW1 or SW4,
pins 8, 9 control SW3 or SW6, and pins 25, 26 control SW2 or SW5.
Switch Indicators
The internal switch positions can be read only when used in the Direct Control method. A
switch position can be read by either a low (0) or high (1) on the A (AI) or B (BI) indicator
lines. The voltage is either 0 or 5 volts depending on the switch position. Low (0) indicates
disabled, and high (1) indicates enabled. Figure 30 shows the rear panel input/output
configuration for port 1. Port 2 is identical to port 1 but where SW1 is replace by SW4, SW2
is replace by SW5, SW3 is replace by SW6 on the RF block diagram. Pins (3,4), (10,11), and
(23,24) are the A and B indicator output pins. Pins 3, 4 indicate SW1 or SW4 position, pins
10, 11 indicate SW3 or SW6 position, and pins 23, 24 indicate SW2 or SW5 position.
Figure 31 on page 37 shows how each switch is configured.

Switch Indicator Function
The 87222C is set to the A or B Position. See Table 6 on page 41, Switch Indicator Voltages
for Test Set Modes. When the switch is set to the A position the Indicator Common is
connected, completing the A Indicator path. The 21 VDC connected to the Indicator
Common is connected to ground by two resistors (30 kΩ and 10 kΩ). The Position A and B
Indicators have independent 10 kΩ resistors to ground. The measured voltage from
Position A Indicator to ground is approximately 5 Volts VDC and the Position B Indicator
will measure 0 Volts. When the switch is set to Position B, the Indicator common is
connected. Measuring the voltage from Position B Indicator to ground will measure
approximately 5 Volts VDC and the A indicator will measure 0 Volts.
Example 1 A Indicator Position Connected

•
Resistance Indicator Common in a connected path = 40 kΩ
Resistance between the Indicator Common and Position A when connected = 30 kΩ
Resistance between Position A and ground = 10 kΩ
Resistance between the Indicator Common and Position B when connected = OPEN
Resistance between Position B and ground = 10 kΩ
1 = V/R = 21/40 kΩ = 0.525 mA
Voltage drop across 30 kΩ resistor: V = 1×R = 0.525 mA×30 kΩ = 15.75 Volts
Voltage drop across 10 kΩ resistor: V = 1×R = 0.525 mA×10 kΩ = Position A indicator to
ground = 5.25 Volts
Being that the Position B switch to the Indicator Common is open, only the 10 kΩ resistor
ground is connected providing a pull down on the Position B Indicator pin, effectively
grounding it.

Controlling the Attenuators
Controlling the attenuators are identical to the Switch Open Collector control method.
Figure 30 on page 37 shows the rear panel input/output configuration for Port 1. Port 2 is
identical to port 1, but ANT1 is replace by ANT2. Pins 13-18 control the attenuator. Like
the switch open collector lines, brake before making the attenuator bypass or select setting
changes.
CAUTION
Always break before making a selection when using the Open Collector
control inputs for the switches and attenuators. Failure to do so can damage
the internal switches or attenuators.
CAUTION
Ensure that all inputs are off before making any connection. Turn off the test
set before removing the connector jumper. Make the rear panel Direct Control

Making High Power Measurements With Option H83
The Z5623AH83 and PNA with Options 014, 016, 080, 081, and UNL or H85 can be
configured to measure high power devices. This ability is useful if the required power for
the device under test is greater than the analyzer can provide, or if the maximum output
power from an amplifier under test exceeds safe input limits for a test set and analyzer.
This section describes how to set up the analyzer to perform high power measurements.
Initial Setup
1. Turn off all of the equipment. Be sure that the jumpers between the PNA and test sets
RCVR 1, RCVR 2, and CPLR THUR are disconnected at this time. This will protect the
PNA from damage.
2. Connect the PNA jumpers for Ports 1 and 2 SOURCE OUT and RCVR IN connectors.
3. Connect the Z5623AH83 to the PNA, see Figure 34, “Setup Configuration.” Depending
on your application set up, not all pulse pattern generators may be required as shown in
this figure.

4. If the Z5623AH83 is in the Shipped mode configuration (all the jumpers are still on)
remove the jumper between AMP OUT and AMP IN connector on the front panel for
Port 1. This can also be done for Port 2 if high power measurements are necessary for
the reverse parameters of a device under test (DUT). Two booster amplifiers are
required for both forward and reverse measurements, see Figure 35.
5. Place four terminations on J1-J4 on the rear panel for AMP 1 and 2.
6. Verify that the Booster Amplifier is turn off at this time.
7. Connect the Booster Amplifier RF INPUT connector to the Port 1 AMP OUT connector
on the front panel of the Z5623AH83.
8. Remove the jumper on the Z5623AH83 between SOURCE OUT and CPLR IN. Place an
isolator or attenuator between the SOURCE OUT and CPLR IN on the port 2 side.

Preset.
11. Turn on the analyzer and decrease the power level to –20 dBm by pressing
[Menu/Dialog] then tab to Channel. In the pull down menu select Power. Scroll to Port
Selection enter [–20]. Select Port Power Coupled to ensure that Ports 1 and 2 power
levels are the same. Uncoupled ports should be used when adjusting the S12 power
level or when Port 1 has a very low power level in comparison to Port 2.
NOTE
Frequency Offset mode (Option 080) and External R1 (Option 081) must be
activated when using the analyzer in a high power configuration. This will
ensure phase lock and allow the R1 and R2 to receive the new reference
power levels from the amplifiers.
- Press [Menu/Dialog] then tab to Channel. In the pull down menu select
Frequency Offset and turn on the Frequency Offset Mode. In the Offset
Setting set the Offset to [0].
- Press [Menu/Dialog] then tab to Channel. In the pull down menu select Test
Set. Select the External R1 Loop in the R1 Input Path window.
12. Set the Z5623AH83 Test Set so that the external booster amplifier is in the RF path.
Refer to “Controlling the Test Set” on page 27 to set the external Booster Amplifier to
be engaged in the RF path.
13. Turn on the booster amplifier.
14. Measure the output power from the booster amplifier RF Output using a power meter

Determining Power Levels
15. Verify the gain of the Booster Amplifier(s). For example; if the analyzer’s output power
level was set to –20 dBm and the output power measured from the open end of the
coupler was –5 dBm, the gain of the booster amplifier would be +15 dB.
16. Verify that the power measured in the previous steps is within the acceptable limits
(less than +43 dBm for the AMP IN port).
17. Turn off the booster amplifier.
18. Estimate the maximum power level that will be needed to force the DUT into
compression. Acceptable limits are less than +43 dBm for the AMP IN port.
CAUTION
Do not command the test set to engage or disengage the amplifier from the
Port 1 RF path while the amplifier is on. This can damage the internal RF
switches in the test set.
19. Verify that the Booster Amplifier is turned off.
20. Connect the Booster Amplifier RF OUTPUT connector to the Port 1 AMP IN connector
on the front panel of the Z5623AH83.
21. Turn on the Booster Amplifier.
22. Using a high power meter and sensor, measure the output power from the test sets

Selecting Power Ranges and Attenuator Settings
Selecting Power Ranges and Attenuator Settings
25. Select a power range that will not exceed the maximum estimated power level, but will
force the DUT into compression. For example; if your Booster Amplifier has a gain of
+15 dB and the DUT will compress if supplied with +15 dBm, then you would adjust
the analyzer’s output power not to exceed 0 dBm. This can done by setting Attenuator
Control to 10 dB by pressing Power, under Attenuator Control, uncheck Auto and enter
[10] into the entry area. In the “Port Selection” area the Port Power Coupled can be
checked to ensure that Port 1 and 2 power levels are the same, or unchecked if Port 1
and 2 power level requirements are different.
26. Estimate the maximum amount of gain that could be provided by the DUT and as a
result, the maximum amount of power that could be received by Test Port 2 when the
DUT is in compression. For example; if a DUT with a maximum gain of +10 dB receives
an input of +10 dBm, then the maximum amount of power that could be received by
Test Port 2 is +20 dBm. An isolator or attenuator may be require depending on the
amount of power at Test Port 2. An isolator is place between the CPLR IN and
SOURCE OUT to protect the test set and the PNA.
27. Calculate the amount of attenuation needed between the analyzer's coupler and
receivers so that you do not exceed the optimum receiver power level of –15 dBm.
Refer to your PNA specifications to optimize power levels to the receiver ports.
It will be necessary to take the following into consideration:
• Power measured at the test sets RCVR R1 OUT = –2 dBm
• Estimated compression power = –2 dBm.
• The optimum PNA receiver power level is –15 dBm
28. Set the internal Z5623AH83 Test Set RCVR R1 step attenuator to the value calculated
below (rounding off to the highest 10 dB step). Refer to “Controlling the Test Set” on
page 27 to set the Attenuator for RCVR R1 OUT path.
With the previous points in mind, the amount of attenuation can be calculated from the
following equations:
Attenuator RCVR R1 Setting = – 2 dBm – ( – 15 dBm )
= 13 dBm
RCVR R1 Attenuatror Value = 20
29. Turn on the Booster Amplifier.
30. Measure the output power from the test sets RCVR R1 using a high power meter
and sensor.
31. Verify that the power measured in the previous step is within the acceptable limits
(–15 dbm at the RCVR R1 OUT).

35. Calculate the amount of attenuation needed between the analyzer's coupler and
receivers so that you do not exceed the optimum receiver power level of –15 dBm.
It will be necessary to take the following into consideration:
• Receiver A will be coupled to the analyzer RF path that could receive power reflections
as high as +10 dBm.
• Receiver B will be coupled to the analyzer RF path that could receive a maximum of
+20 dBm from the DUT.
• Analyzer coupler loss is –13 dB.
• The optimum receiver power level is –15 dBm.
36. Set the internal step attenuator to the value calculated below (rounding off to the
highest 5 dB step). Setting the receiver attenuation will set the internal attenuation.
Press [Menu/Dialog] then tab to Channel. In the pull down menu select Power, under
Receiver Attenuation set Receiver A to [10] and Receiver B to [20]. Power levels greater
than +35 dBm will require additional attenuation between Port 2, access ports CPLR
ARM and RCVR B IN.
With the previous points in mind, the amount of attenuation can be calculated from the
following equations:
Receiver Attenuator A = 10 dBm – 13 dBm – ( – 15 dBm )
Attenuator A = 12 dBm
Receiver Attenuator B = 20 dBm – 13 dBm – ( – 15 dBm )

45. Turn on the DUT and measure the S21 gain of the amplifier under test to confirm the
proper operation of the measurement test setup.
46. Continue with any other high power measurements.
NOTE
Ratio measurements, such as gain, will be correctly displayed. However, the
displayed absolute power levels on the analyzer will not be correct. To
correctly interpret power levels and the gain of the booster amplifier, the
attenuator setting must be taken into consideration.
If no calibration has been performed or if the instrument is in an un-calibrated state, the
following must be taken into consideration when interpreting the measured data:
• The value of attenuation added to receiver A and B.
• The R channel reference level supplied from the test set.
• Protection of the internal parts for the test set and PNA.
This procedure can be repeated to setup the reverse high power configuration.

Test Set Internal Configurations
Test Set Internal Configurations
The Z5623AH83 can be internally configured to allow the user to configure it for different
application requirements. In this section we will show the test sets internal configurations.
The Test Sets Port 1 side is a mirror image of the Port 2 side. Both sides are independent of
each other.
For simplicity the Port 1 side will be used for the following examples.
There are four basic mode configurations.
• Bypass
• High Power
• Pulse
• Pulse High Power
• Amplifier Terminate
Bypass
The bypass mode sets the Test Set’s internal switches so that the SOURCE IN port thru
path connects directly to the CPLR THRU port. This allows you to use the PNA in a
normal operation. The test port and R1 reference power at the PNA will be reduced due to
the loss of the test set. Figure 38 shows the main signal flow through the test set Port 1
side, which is identical to the Port 2 side.

Test Set Internal Configurations
High Power
The high power mode sets the Test Set’s internal switches so that the SOURCE IN port
thru path connects to the AMP OUT and AMP IN ports, and then to the CPLR THRU port.
This allows the user to insert a Booster Amplifier in the RF path. Figure 39 shows the
main signal flow through the test set Port 1 side, which is identical to the Port 2 side.
Figure 39
High Power
Pulse
The pulse mode sets the Test Set’s internal switches so that the SOURCE IN port thru
path connects to the PIN switch modulator, directly to the CPLR THRU port. This allows
the user to make lower power pulse measurement. Figure 40 shows the main signal flow
through the test set Port 1 side, which is identical to the Port 2 side.

The pulse high power mode sets the Test Set’s internal switches so that the SOURCE IN
port thru path connects to the PIN switch modulator, then to the AMP OUT and AMP IN
ports, and then to the CPLR THRU port. This allows user to insert a booster amplifier in
the pulsed RF path. Figure 41 shows the main signal flow through the test set Port 1 side,
which is identical to the Port 2 side.

Amplifier Terminate
The terminate amplifier is set in the bypass and pulse mode. This sets the Test Set’s
internal switches so that the AMP IN and AMP OUT RF ports are routed to the rear panel
Amp Term 1 ports. Customer furnished terminations can be connected to these ports so
that you may customize your power requirements. This allows the user to terminate the
Booster Amplifiers input and output. Figure 42 shows the main signal flow through the

Procedure
To test the performance of the Z5623AH83 this document assumes that the user is familiar
with the necessary equipment. The PNA USB keyboard and mouse will necessary to enter
GPIB commands and to read the trace data. Measurements can be made easier by setting
up Markers with search, tracking, and search domain user states for each of the frequency
bands.
Using the PNA as the controller to issue commands to the Z5623AH83 Test Set can be
found in “Controlling the Test Set” on page 27.
General S-Parameters are used to characterize the connection paths of the test set. Both
reflection and transmission measurements are required. These measurements are made
with the E8362B, 3.5 mm calibration kit and RF cables. Power Output and Pulse Shape
are not measured to re-verify the Z5623AH83 test set.
A Full 2-Port SLOT (short, load, open, thru) Calibration should be performed on the PNA
